One of the eight atom classes used to describe atoms in LPC:
- I = 'Hydrophilic'
- II = 'Acceptor'
- III = 'Donor'
- IV = 'Hydrophobic'
- V = 'Aromatic'
- VI = 'Neutral'
- VII = 'Neutral-donor'
- VIII = 'Neutral-acceptor'
String of length 8 which uniquely identifies a ligand from a
PDB file. It consists in the concatenation of the "Residue
Name" (*), of the "Chain Identifier" (*) and of the "Residue
Sequence Number" (*).
(*) see PDB format, HETATM field.
Single character which identifies the residue type. It is
limited to the 20 usual residue one-letter codes, and to 'X'
which stands for anything else.
3-letter string which identifies the residue type. It is
not restricted to a predefined list of three-letter codes, so
as to allow for unusual residue types (i.e. 'HSE', or 'GLX').
String of length 4, starting with a number between 1 and 9
(both inclusive), followed by three alphanumeric characters.
