==Aspartyl Dipeptidase==
-
The three-dimensional structure of Salmonella typhimurium aspartyl, dipeptidase, peptidase E, was solved crystallographically and refined to, 1.2-A resolution. The structure of this 25-kDa enzyme consists of two, mixed beta-sheets forming a V, flanked by six alpha-helices. The active, site contains a Ser-His-Glu catalytic triad and is the first example of a, serine peptidase/protease with a glutamate in the catalytic triad. The, active site Ser is located on a strand-helix motif reminiscent of that, found in alpha/beta-hydrolases, but the polypeptide fold and the, organization of the catalytic triad differ from those of the known serine, proteases. This enzyme is a member of a family of serine hydrolases and, appears to represent a new example of convergent evolution of peptidase, activity.
