General annotation (Comments)

Function

Dual metabolic roles of gluconeogenesis (in the mitochondria) and glyoxylate detoxification (in the peroxisomes).

Catalytic activity

L-serine + pyruvate = 3-hydroxypyruvate + L-alanine.

L-alanine + glyoxylate = pyruvate + glycine.

Cofactor

Pyridoxal phosphate.

Subcellular location

Mitochondrion matrix. Peroxisome. Note: Induced on glucagon administration. Not affected by glucagon.

Sequence similarities

Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family.
