Diaminopimelate epimerase signature


Diaminopimelate epimerase (EC catalyzes the isomeriazation of L,L- to D,L-meso-diaminopimelate in the biosynthetic pathway leading from aspartate to lysine.

This enzyme is a protein of about 30 Kd. Two conserved cysteines seem [1] to function as the acid and base in the catalytic mechanism. As a signature pattern, we selected the region surrounding the first of these two active site cysteines.
