YcjG

__**YcjG: L-Alanyl-D/L-Glutamate Epimerase**__

The YcjG protein is an epimerase belonging to the enolase superfamily.

It catalyses the inversion of the stereochemistry of the dipeptide L-Ala-D-Glu to form L-Ala-L-Glu. L-Ala-L-Glu can then act as a substrate for PepD, a dipeptidase of E. coli with broad specificity.

Since it is a member of the enolase superfamily of enzymes, it requires a divalent metal ion (LOOK UP WHICH ONE) to work.
