	2.6.1.45
Description	Serine--glyoxylate aminotransferase.
Alternative names	SGAT.
Catalyzed reaction	L-serine + glyoxylate = 3-hydroxypyruvate + glycine.
Cofactor	Pyridoxal-phosphate.
	The Arabidopsis enzyme also shows alanine-glyoxylate aminotransferase activity (2.6.1.44), but serine is the preferred substrate.
