abstract：:Zinc metallopeptidases that contain the His-Glu-Xaa-Xaa-His (HEXXH) motif generally have a third ligand of the metal ion that may be either a Glu residue (in clan MA) or a His residue (in clan MB) (Rawlings and Barrett (1995) Methods Enzymol. 248, 183-228). Thimet oligopeptidase has not yet been assigned to either cla...
