The first column is a factor containing the codon. The second column is a factor giving the aminoacids names for each codon. The last column is a factor giving the IUPAC one-letter code for aminoacids} \item{AA.PROPERTY}{is a list giving the physico-chemical class of amino acid. The differents classes are the following one : Tiny, Small, Aliphatic, Aromatic, Non.polar, Polar, Charged, Basic, Acidic } \item{pK}{is a data frame. It gives the pK values of amino acids described in Bjellqvist \emph{et al.} (1993) , which were defined by examining polypeptide migration between pH 4.5 to 7.3 in an immobilised pH gradient gel environment with 9.2M and 9.8M urea at 15 degree or 25 degree} } } \source{ Data prepared by D.
