In enzymology, a serine-glyoxylate transaminase () is an enzyme that catalyzes the chemical reaction L-serine + glyoxylate 3-hydroxypyruvate + glycine Thus, the two substrates of this enzyme are L-serine and glyoxylate, whereas its two products are 3-hydroxypyruvate and glycine. This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is L-serine:glyoxylate aminotransferase. This enzyme participates in glycine, serine and threonine metabolism. It employs one cofactor, pyridoxal phosphate. References EC 2.6.1 Pyridoxal phosphate enzymes Enzymes of unknown structure
