  • Title: Isolation of the aspartokinase domain of bifunctional aspartokinase I-homoserine dehydrogenase I from E.coli K12.
    Author: Veron M, Guillou Y, Cohen GN.
    Journal: FEBS Lett; 1985 Feb 25; 181(2):381-4. PubMed ID: 2982665.
    Abstract:
    A proteolytic fragment (Mr approximately 25 000) carrying only the aspartokinase activity has been purified by chromatofocusing after limited proteolysis of aspartokinase I-homoserine dehydrogenase I from E.coli K12. The NH2-terminal sequence shows that it corresponds to the amino terminal peptide of the native enzyme. The results confirm a previous hypothesis about the organization of native aspartokinase I-homoserine dehydrogenase I.
