In enzymology, an amino-acid racemase (EC 5.1.1.10) is an enzyme that catalyzes the chemical reaction Hence, this enzyme has one substrate, L-amino acid, and one product, D-amino acid.
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 amino-acid racemase.
This enzyme is also called L-amino acid racemase.
As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes 2FKP, 2GGG, 2GGH, 2GGI, and 2GGJ.
