Diaminopimelate epimerase

In enzymology, a diaminopimelate epimerase is an enzyme that catalyzes the chemical reaction


 * LL-2,6-diaminoheptanedioate $$\rightleftharpoons$$ meso-diaminoheptanedioate

Hence, this enzyme has one substrate, LL-2,6-diaminoheptanedioate, and one product, meso-diaminoheptanedioate.

This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on amino acids and derivatives. The systematic name of this enzyme class is LL-2,6-diaminoheptanedioate 2-epimerase. This enzyme participates in lysine biosynthesis.
