Protein
L-Ala-D/L-Glu epimerase
Organism
Thermotoga maritima (strain ATCC 43589 / MSB8 / DSM 3109 / JCM 10099)
Function
Catalyzes the epimerization of L-Ala-D-Glu to L-Ala-L-Glu and has probably a role in the metabolism of the murein peptide, of which L-Ala-D-Glu is a component. Is also able to catalyze the reverse reaction and the epimerization of a broad range of other dipeptides; is most efficient with L-Ala-D/L-Phe, L-Ala-D/L-Tyr, and L-Ala-D/L-His.
Similarity
Belongs to the mandelate racemase/muconate lactonizing enzyme family.
