Gly341-Pro349), packs against multiple hydrophobic C2 domain residues (e.g., Leu353, Leu323, Leu402). In the variant simulations, the thioether side chain of Met348 can form similar interactions as valine due to its comparable hydrophobic profile. In fact, the thioether group of methionine can even stack favorably with the phenol ring of Tyr363 in the anti-parallel β sheet strand (res. Ala399-Ile411). Overall, the residue swap does not appear to cause negative effects on the protein structure based on the simulations.

Gly341-Pro349), allows the strand to end and make a tight turn before a short α helical section within a loop connecting to another β strand (res. Thr359-Pro364). In the variant simulations, the hydroxyl group of Ser349 forms a hydrogen bond with the backbone amide group of Ala351 in the short helical section. Conversely, the backbone amide group of Ser349 (absent in proline) does not form any intra-protein hydrogen bonds. However, the β strand end connects to the α helical section in a more stable and consistent manner compared to the WT. Although the residue swap does not cause major adverse effects on the protein structure in the simulations, it is possible that the tight turn at the β strand end could not be created during folding without the presence of proline.

Because the Ω loop is assumed to directly interact with the membrane, it moves arbitrarily throughout the WT solvent simulations. The Ω loop potentially plays a crucial role in the SynGAP-membrane complex association, stability, and dynamics. However, this aspect cannot be fully addressed through solvent simulations alone.Ω loops are known to play major roles in protein functions that require flexibility, and thus, large and relatively hydrophobic residues like tyrosine are rarely tolerated. Additionally, the hydroxyl group of Tyr374 frequently forms various hydrogen bonds with other loop residues in the variant simulations. Although no negative structural effects are observed in the variant simulations, Tyr374 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. However, since the effect on Gly-rich Ω loop dynamics can only be studied through the SynGAP-membrane complex, no definite conclusions can be drawn.

The Ω loop is assumed to directly interact with the membrane, and it is observed to move arbitrarily throughout the WT solvent simulations. This loop potentially plays a crucial role in the SynGAP-membrane complex association, stability, and dynamics. However, this aspect cannot be fully addressed through solvent simulations alone.Ω loops are known to play significant roles in protein functions that require flexibility, and so they are rich in glycine residues, prolines, and to a lesser extent, small hydrophilic residues to ensure maximum flexibility. Thus, the variant’s Glu390 may not be as well tolerated in the Ω loop. Additionally, the carboxylate group of Glu390 occasionally forms H-bonds with other loop residues in the variant simulations. The interaction between the acidic carboxylate side chain and the acidic membrane lipids may further influence the SynGAP-membrane complex. However, since the effects on the Gly-rich Ω loop dynamics can only be well studied through the SynGAP-membrane complex, no definite conclusions can be drawn.

The Ω loop is assumed to directly interact with the membrane, and it is observed to move arbitrarily throughout the WT solvent simulations. Although the residue swap does not influence the nearby secondary structure elements, proline is often found at the ends of β sheets due to its disfavored status during folding.Additionally, the Ω loop potentially plays a crucial role in the SynGAP-membrane complex association, stability, and dynamics. However, this aspect cannot be fully addressed through solvent simulations alone. Ω loops are known to play significant roles in protein functions that require flexibility, and thus hydrophobic residues like leucine are rarely tolerated. Although no negative structural effects are visualized in the variant’s simulations, Leu398 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. Since the effects on the Gly-rich Ω loop dynamics can only be well studied through the SynGAP-membrane complex, no definite conclusions can be drawn.

In the variant simulations, the indole ring of the Trp429 side chain cannot form ionic interactions with the acidic residues. Although it forms a H-bond with Ser471, the bonding is not as strong as that of arginine. The residue swap could affect the tertiary structure assembly during folding; however, no large-scale negative effects were seen during the simulations.

Although the residue swap does not negatively affect the protein structure based on the simulations, it is noteworthy that the residue faces the RasGTPase interface.

It also forms a hydrogen bond with the backbone carbonyl group of Cys552, which weakens the α-helix integrity. In the variant simulations, the hydroxyl group of Ser556 forms a more stable hydrogen bond with the backbone carbonyl oxygen of the same helix residue, Cys552, compared to Asn556 in the WT. Serine has a slightly lower propensity to reside in an α-helix than asparagine, which may exacerbate the negative effect on the α-helix integrity.

Instead, His575 only forms weak hydrogen bonds with the hydroxyl groups of Ser466 and Ser571. Overall, the residue swap has the potential to substantially affect the tertiary structure assembly during the protein folding process.

Glu582-Met603).In the variant simulations, the side chain of Ser635 is shorter than asparagine and thus prefers to hydrogen bond with the carbonyl group of Gln631 on the same helix and, to a lesser extent, with Ser590 compared to Asn635 in the WT. Ser635 forms hydrogen bonds with the backbone atoms of the same helix, which may destabilize the helix, although this is not clearly evident in the simulations. The weakening of the hydrogen bond between Ser635 and Ser590 in the variant may also weaken the tertiary structure assembly between the helices.Additionally, Asn635 is at the GTPase interface. However, the implication of the residue swap on the complex formation with the GTPase cannot be investigated using solvent-only simulations.

Ser641-Glu666 and res. Leu685-Val699), is involved in a highly coordinated hydrogen-bonding network between residues from two α-helices (res. Ser641-Glu666 and res. Arg563-Glu578) and from the α-α loop itself, such as Lys566, Glu666, and Asn669. Met672 can only form a hydrogen bond with the amino group of the Lys566 side chain via its backbone carbonyl group. Nevertheless, the Lys566-Glu666 salt bridge forms intermittently. This is possible because Asn669 keeps the carboxylate group of Glu666 in the vicinity through hydrogen bonding, and the hydrophobic side chain of Met stays mostly rotated away from the salt bridge. Consequently, no drastic disruption of the hydrogen-bond network that keeps the loop close to the helices occurs in the variant simulations.

Consequently, the Gln272 side chain is freer to interact with the loop residues than Arg272, potentially negatively affecting the dynamic SynGAP-membrane association.

In the WT simulations, the Arg299 side chain hydrogen bonds with the loop backbone carbonyl groups (e.g., Ser302, Thr305, Leu274, Gly303), the hydroxyl group of Ser300, and even forms a salt bridge with the carboxylate group of Asp304.In the variant simulations, the imidazole ring of His299 (epsilon protonated state) hydrogen bonds with the carbonyl group of Asp304 and the hydroxyl group of Ser300. However, it does not form as many or as strong interactions as arginine, which could affect the initial formation of the secondary hairpin loop during folding. β hairpins are potential nucleation sites during the initial stages of protein folding, so even minor changes in them could be significant.Additionally, His299 prefers to hydrophobically interact with other hydrophobic residues inside the C2 domain core (e.g., Val306, Leu274), which destabilizes the C2 domain. Indeed, the β strand partially unfolds during the second simulation. Moreover, the positively charged Arg299 side chain faces the polar head group region of the inner leaflet membrane and could directly anchor the C2 domain to the membrane. In short, the residue swap could negatively affect both protein folding and the stability of the SynGAP-membrane association.

However, the carboxamide group of the Asn352 side chain does not form hydrogen bonds with the backbone carbonyl group of Pro349. Instead, it packs against the cyclic ring and forms hydrogen bonds with the phenol group of the Tyr363 side chain in the other β strand.

Because, the Ω loop is assumed to be directly interacting with the membrane, it is only seen to move arbitrarily throughout the WT solvent simulations. The Ω loop is potentially playing a crucial loop in the SynGAP-membrane complex association, stability and dynamics, regardless, this aspect cannot be addressed through the solvent simulations only. The Ω-loops are known to have a major role in protein functions that requires flexibility and thus, they are rich in glycines, prolines and to a lesser extent, hydrophilic residues to ensure maximum flexibility. Thus, Ser370 in the variant is potentially tolerated in the Ω loop. However, since the effect on the Gly-rich Ω loop dynamics can only be well-studied through the SynGAP-membrane complex, no definite conclusions can be withdrawn.

In the variant simulations, the hydroxyl group of Thr501 forms a hydrogen bond with the backbone atoms of Tyr497 on the same α-helix, which may weaken the α-helix integrity. Additionally, the polar hydroxyl group of Thr501 is not suitable for the hydrophobic inter-helix space, and thus, the residue swap could affect protein folding. However, Ile501 is followed by Gly502, which facilitates a hinge in the middle of the α-helix, making further weakening caused by Thr501 unlikely to be harmful to the α-helix integrity.

These hydrogen bonds disrupt the structure of the terminal end of the α-helix (Ala533-Ser535), causing it to weaken or unfold during the WT simulations. In the variant simulations, Thr535, a hydrophilic residue with a hydroxyl group of almost the same size as Ser, interacts more frequently with the preceding loop residues (e.g., Thr532, Cys531) due to its longer side chain.
