  • Title: E. coli aspartokinase II-homoserine dehydrogenase II polypeptide chain has a triglobular structure.
    Author: Belfaiza J, Fazel A, Müller K, Cohen GN.
    Journal: Biochem Biophys Res Commun; 1984 Aug 30; 123(1):16-20. PubMed ID: 6383377.
    Abstract:
    E.coli aspartokinase II-homoserine dehydrogenase II is, as aspartokinase I-homoserine dehydrogenase I, composed of three globular domains: the N-terminal domain is endowed with kinase activity; the C-terminal domain carries the dehydrogenase activity. These two parts of the polypeptide chain are separated by a central inactive domain. Thus, the polypeptide chains of the two multifunctional proteins are homologous not only in their sequence but also in their triglobular domain structure.
