(Fig.1and Supplementary Fig.1). The structure reported here comprises residues Ser31-Gln292 visible in the electron density map. The refined structure was in good agreement with the X-ray crystallographic statistics for bond angles, bond lengths, and other geometric parameters (Supplementary Table1...

When this is not the case, the bond angles deviate from these values in sometimes predictable ways. Because a lone pair tends to require more space than a bonding pair, it tends to reduce the bond angles. 10 | 34 The impact of lone pair(s) on bond angle for tetrahedral electron-pair ...
Since bond rotations are periodic, the adversarial distortion δ does not break the geometries apart, a concern that exists in many other ML-accelerated simulations as in the previous section. Nevertheless, some angles (φ, ψ) may lead to high-energy configurations depending on the conformation ...
