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.

Thr704-Gly712), forms a salt bridge with Lys710 and a hydrogen bond with its own backbone amino group at the helix end in the WT simulations. Although Lys706 is unable to make these transient interactions in the variant simulations, there is no apparent negative effect on the protein structure due to the residue swap. However, because the model ends abruptly at the C-terminus, no definite conclusions can be drawn based on the simulations.

Ala533-Val560). The methyl group of Ala541 is on the surface and does not form any interactions. Glycine, known as an “α-helix breaker,” weakens the integrity of the helix. Indeed, in the variant simulations, the hydrogen bond formation between Gly541 and the backbone carbonyl of Ala537 is disrupted.

Ile205-Pro208), is replaced by a positively charged lysine. On the protein surface, both the carboxamide group of Asn199 and the amino group of Lys199 side chains can form hydrogen bonds with the backbone carbonyl groups of residues (e.g., Ala249) at the end of an α helix (res. Ala236-Lys251). However, since the model ends abruptly at the N-terminus, no definite conclusions can be drawn from the simulations.

Arg563-Glu578), where its methyl group does not form any particular interactions in the WT simulations. In the variant simulations, the hydroxyl group of the Thr577 side chain hydrogen bonds with the backbone atoms of Arg573 and Lys574 within the same helix, which has the potential to weaken the stability of the secondary structure element. Regardless, the residue swap seems to be well tolerated based on the variant simulations.

Thr305-Asn315, res. Ala322-Asp330), faces outward without forming any stable interactions in the WT simulations. Similarly, in the variant simulations, the imidazole ring of His321 also points outward without making any stable intra-protein interactions. Thus, the residue swap does not seem to cause adverse effects on the protein structure based on the simulations. However, β hairpins are potential nucleation sites during the initial stages of protein folding, so even minor changes in them could be significant.

Thr228-Ala232), forms hydrogen bonds with nearby residues Glu217, Cys233, and Cys219 in the variant simulations. These hydrogen-bonding interactions at the β sheet surface contribute to the stability of the secondary structure element and prevent it from unfolding. The new hydrogen bond interactions may be more favorable for structural stability than the steric interactions of the methyl side chain of Ala with the side chains of Gln216 and Cys219 in the WT. However, since the model ends abruptly at the N-terminus, no definite conclusions can be drawn from the simulations.

Met414-Glu436), either forms a salt bridge with the carboxylate group of an acidic residue (Asp474, Asp467) or an H-bond with the hydroxyl group of Ser471 in an opposing α helix (res. Ala461-Phe476). In the variant simulations, Gln429 cannot form ionic interactions with the acidic residues; however, the carboxamide group can form multiple H-bonds. The H-bonding coordination of the Asn429 side chain varied between the replica simulations. In one simulation, three H-bonds were formed simultaneously with the Asp467 side chain, the backbone carbonyl group of Asn426, and the amide group of Met430 at the end of the same α helix. The residue swap could affect the tertiary structure assembly during folding due to weaker bond formation, but no large-scale negative effects were seen during the simulations.

Pro364-Pro398) between two anti-parallel β sheet strands (res. Thr359-Pro364, res. Ala399-Ile411). 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.

Ala461-Phe476), packs with the hydrophobic side chains of Leu482 and Ile483. Additionally, Phe476 stacks with the Arg475 side chain on the preceding α-α loop connecting the two α-helices (res. Ala461-Phe476 and res. Leu489-Glu519) near the GAP-Ras interface.In the variant simulations, Leu476 can maintain hydrophobic packing with neighboring residues, although not as efficiently as the phenylalanine in the WT system. The absence of Phe476/Arg475 stacking weakens the integrity of the α-helix end in the variant simulations. Nonetheless, no large-scale adverse effects are observed in the simulations. Lastly, the potential effect of the residue swap on SynGAP-Ras complex formation or GTPase activation cannot be fully addressed using the SynGAP solvent-only simulations.

Gly341-Pro349, res. Thr359-Pro364) originating from two different anti-parallel β sheets of the C2 domain. In the WT simulations, the side chain hydroxyl and backbone amide groups of Thr354 form hydrogen bonds with the backbone carbonyl group of Pro349 at the end of the preceding β strand. This arrangement likely stabilizes the α helical section and aids in folding, keeping the short secondary structure element intact in the variant simulations. 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.

Gly502-Tyr518 and Ala533-Val560) facing the membrane. In the WT simulations, the hydroxyl group of Thr532 occasionally forms hydrogen bonds with the backbone atoms of other loop residues without any specific interaction. In the variant simulations, the Pro532 residue swap does not cause structural changes. Although hydrophilic residues seem more favorable in the loop, the pyrrolidine side chain of proline is well suited for unstructured protein regions such as loops. However, due to its location at the SynGAP-membrane interface, the effect of the residue swap cannot be fully addressed using the SynGAP solvent-only simulations.

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.

Ser641-Glu666 and res. Leu685-Val699), is sterically packed against His453 and Glu688. In the variant simulations, the iso-propyl side chain of Val683 has similar size and physicochemical properties as Ile630 in the WT, and thus, it is able to maintain similar interactions in the inter-helix space. Consequently, no negative structural effects are observed during the simulations due to the residue swap.

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 hydrophobic residues like leucine are rarely tolerated. Although no negative structural effects are observed in the variant simulations, Leu385 may exert drastic effects on the SynGAP-membrane complex dynamics and stability. However, since the effects on Gly-rich Ω loop dynamics can only be studied through the SynGAP-membrane complex, no definite conclusions can be drawn.

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 so they are rich in glycines, prolines, and, to a lesser extent, small hydrophilic residues to ensure maximum flexibility. Thus, the variant’s Ser384 is potentially tolerated in the Ω loop, although the hydroxyl group of Ser384 forms various hydrogen bonds with several other loop residues in the variant simulations.
