Description Alanine--glyoxylate aminotransferase.
Alternative names L-alanine-glyoxylate transaminase;
L-alanine-glycine transaminase;
Catalyzed reaction L-alanine + glyoxylate = pyruvate + glycine.
Cofactor Pyridoxal-phosphate.
Comments -!- With one component of the animal enzyme, 2-oxobutanoate can replace glyoxylate. A second component also catalyzes the reaction of EC
The isoenzyme alanine:glyoxylate aminotransferase 1 from rat liver organelles is identical to serine-pyruvate aminotransferase ( and asparagine-oxo-acid aminotransferase ([Noguchi & Fujiwara (1988) JBC 263, 182]. Sequences for this enzyme are listed under

The eukariotic sequences included in family a are close homologs of alanine:glyoxylate aminotransferase 2 from rat liver; this enzyme appears to be identical to (D)-3-amino-2-methylpropanoate aminotransferase ( and aminolevulinate aminotransferase (

The archaeal sequences included in family b are not closely related to the eukariotic enzymes with alanine-glyoxylate aminotransferase activity.

Diseases Primary hyperoxaluria type 1 (?) Hyper-beta-aminoisobutyricaciduria (?)
