Single-Letter Codes and Molecular Masses of Amino Acids

6 Single-Letter Codes and Molecular Masses of Amino Acids [Pg.222]

The single-letter code is helpful to describe longer amino acid sequences. It is derived from the three-letter code of amino acids (aa). [Pg.222]

Checking number CN and reference number AA is used for unequivocal characterization of each amino acid sequence [Pg.222]

Sequence (lUPAC-IUB) His-Clu-Leu-Pro-Met-Ala-Thr-His-Clu Single-letter code HELPMATHE [Pg.222]

CN checking number AA reference number (cf Table 8.13) i position number of the respective aa within the sequence (i of the N-terminal aa is 1) NR total number of aa within the polypeptide chain Mr molar mass of the polypeptide COMP true formula of the polypeptide (all naturally occurring aa have to be listed, aa which are no part of the chain are indicated by 0 ).
