  • Title: The primary structure of Escherichia coli K12 aspartokinase I-homoserine dehydrogenase I. Site of limited proteolytic cleavage by subtilisin.
    Author: Briley PA, Sibilli L, Chalvignac MA, Cossart P, Le Bras G, De Wolf A, Cohen GN.
    Journal: J Biol Chem; 1978 Dec 25; 253(24):8867-71. PubMed ID: 363710.
    Abstract:
    The sequence of the first 25 residues of the homoserine dehydrogenase fragment, produced by limited proteolysis of aspartokinase I-homoserine dehydrogenase I with substilisin, has been determined. The sequence of a cyanogen bromide peptide (CB5, 59 residues), isolated from the entire protein, is also presented. Residues 1 to 18 of the subtilisin homoserine dehydrogenase fragment match the sequence 42 to 59 of peptide CB5.
