A correction and extension of the acetylated amino terminal sequence of ovalbumin.
The acetylpeptides derived from S-carboxymethylovalbumin by cyanogen bromide and chymotrypsin have been isolated and shown by enzyme digestion and the dansyl-Edman method to fit the sequence acetyl-Gly-Ser-Ile-Gly-Ala-Ala-Ser-Met-Glu-Phe. This corrects the order of the third and fourth residues in the five-residue sequence given by Narita and Ishii [J. Biochem. (Tokyo), 1962, 52, 367--73]. The overlap of the C-terminal sequence of this extended sequence with the six-residue N-terminal sequence surrounding a half-cystine residue in ovalbumin gives the N-terminal sequence for ovalbumin as acetyl-Gly-Ser-Ile-Gly-Ala-Ala-Ser-Met-Glu-Phe-Cys-Phe-Asp-Val-Phe-Lys with residue 11 a cysteine residue.[1]References
