# Amino acid properties file.
# For molecular weights see Emolwt.dat

#  Tiny, Small, Aliphatic, Aromatic, Non-polar, Polar, Charge, +ve, -ve Ext
#
# Extinction coefficients up to EMBOSS 6.2.0 were based on the values
# of Gill and von Hippel (1989) _Anal_Biochem_ 182 319-326.
#
# In EMBOSS 6.3.0 we updated to use values from Pace et al. (1995)
# Protein Sci. 11, 2411-2423. These give better predictions for a set
# of 116 measurements of Tryptophan-containing proteins.
#
# Cysteine extinction values is for proteins with disulphide bridges
# as cystine. For reduced residues there is no contribution and the
# value is zero.
#
# Values for Selenocysteine copied from Cysteine
#
# J is an ambiguity code for Isoleucine or Leucine for Mass Spec data
# These have identical properties in this file.
#
# O is pyrrolysine in Archaea.
# Properties assumed to be the same as lysine
