Start and structure of OdhA. The N-terminal ends are shown for OdhA of C. glutamicum (OdhA-Cg), Mycobacterium leprae (OdhA-Ml), Kgd of M. tuberculosis (Kgd-Mt), OdhA of Corynebacterium diphtheriae (OdhA-Cd), and SucA, E1o of E. coli (SucA-Ec). The annotated initiating methionines are given in boldface, and the sequence of OdhA-Cg determined by Edman degradation is underlined. The sequences were aligned using Clustal. The structural predictions as obtained for OdhA of C. glutamicum are given at the top, and that for SucA of E. coli at the bottom. The prediction was made with PredictProtein, and “rel sec” is the reliability index (0 = low and 9 = high), for either loop, L, or helix, H, given in “sub sec.” Asterisks, periods, and colons denote the degree of similarity of the amino acids.
