Differential distribution of side-chain and main-chain rotors among representative amino acid sets.

Abstract

<p>Dissimilar ϕ vs χ₁ basins in protein structures for various amino acid types. Differential basin preferences for different amino-acids are calculated from the entire database of 22,977 non-redundant structures. Localization for the χ₁ and ϕ dihedral rotors in protein structures are evident.</p
