Thus, the two substrates of this enzyme are L-methionine and glyoxylate, whereas its two products are 4-methylthio-2-oxobutanoate 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-methionine:glyoxylate aminotransferase. Other names in common use include methionine-glyoxylate aminotransferase, and MGAT.
