Atom parameters and definitions for side chains
Description
List of the atom dependencies and typical bond parameters in protein structures for side chains of the 20 standard amino acid types.
Usage
atomdeps
Format
A list for the 20 amino acid types, each having the attributes
"tangle": Dihedral angle defined by atoms A-B-C-D as described below.
NA's represent the free side chain dihedral angles chi for that amino acid."names": The component atoms of the amino acid side chain. Represents atom D in the dihedral.
"matx": The names of atoms A,B,C in the dihedral, with rows corresponding to the atoms in "names".
"bangle": Planar bond angle formed between B-C-D
"blength": Bond length between C-D
