# protons. The original version of this table was created by Charles
# Hoogstraten.
#
# BMRB = System in use at BioMagResBank (IUPAC/IUB Biochemistry 9, 3471-3479
# [1970]).
#
# SC = Stereochemical designations
#
# UCSF = Mardigras-type software (peptide protonated with newhyd utility).
#
# XPLOR = Peptide protonated with XPLOR 3.1. Atom nomenclature is derived
# from the X-PLOR topology file topallhdg.pro.
#
# MSI = Artificial peptide created with InsightII. For the side chain
# protons attached to nitrogen in ASN, GLN, and ARG, the atom
# nomenclature does not reflect the potential stereoisomerism of the
# planar amide and guanidinium groups. The correlation with Z and E
# nomenclature listed here simply reflects the state of the artificial
# peptide generated as an example. The CG1 and CG2 atoms for VAL in a
# peptide generated by InsightII are not labeled according to IUPAC
# rules, while the CD1 and CD2 atoms for LEU are.
#
# PDB = PDB nomenclature (Taken from PDB entry 6I1B REVDAT 15-OCT-92.)
#
# SYBYL = The atom nomenclature was taken from the xxx.res files supplied with
# the software package Sybyl version 6.2 from Tripos, Inc.
#
# MIDAS = MidasPlus from the Computer Graphics Laboratory at UCSF. The atom
# nomenclature has been taken from the XXX.ins files supplied with the
# software. The prochiral atoms have not been correlated with the
# BMRB assignments at this time. Hydrogens are not included in the
# XXX.ins template files.
#
# Note-1: The prochiral methyl group names may reflect convention of code
# generating heavy atom names if protons are added later.
#
# Note-2: '*' The stereochemical assignments for the named atoms have not been
# determined for these software systems.
#
# Note-3: The Z and E nomenclature is defined in the paper by Blackwood, J.E.,
# Gladys, C.L., Loening, K.L., Petrarca, A.E., and Rush, J.E.,
# "Unambiguous Specification of Stereoisomerism about a Double Bond,"
# J. Amer. Chem. Soc. 90, 509-510 (1968).
#
# Note-3: For the terminal amine and carboxyl atoms, 'X' has been used as a
# dummy value for the amino acid type.
#
# Note-4: The terminal secondary amine protons for PRO have been included
# with the other PRO atoms.
#
# Note-5: Fields in the table are separated by tabs.
#
# Note-6: Please report errors, updates, or extensions to Eldon Ulrich
