Function

NSAR_AMYSP Acts as a N-succinylamino acid racemase (NSAR) that catalyzes the racemization of N-succinyl-phenylglycine and N-succinyl-methionine (PubMed:14705949, PubMed:24955846). Can catalyze the racemization of a broad range of N-acylamino acids, including N-acetyl-D/L-methionine, N-propionyl-D/L-methionine, N-butyryl-D/L-methionine and N-chloroacetyl-L-valine (PubMed:7766084, PubMed:10194342, PubMed:14705949, PubMed:23130969). Also converts 2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate (SHCHC) to 2-succinylbenzoate (OSB) (PubMed:10194342, PubMed:14705949, PubMed:24955846). Catalyzes both N-succinylamino acid racemization and OSB synthesis at equivalent rates (PubMed:14705949, PubMed:24955846). NSAR is probably the biological function of this enzyme (Probable).^{[1] [2] [3] [4] [5] [6] [7]}
