SEQINR.UTIL: utility data for seqinr

Description

This data set gives the genetics code, the name of each codon, the IUPAC one-letter code for aminoacids and the physico-chemical class of amino acid and the pK values of amino acids described in Bjellqvist et al. (1993).

Format

SEQINR.UTIL is a list containing the 4 following objects:

CODES.NCBI

is a data frame containing the genetics code : The standard ('Universal') genetic code with a selection of non-standard codes.

CODON.AA

is a three columns data frame. 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

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

pK

is a data frame. It gives the pK values of amino acids described in Bjellqvist 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
