Cofactor	Pyridoxal phosphate. Ref.1
Enzyme regulation	Inhibited by aminooxyacetate. Ref.1
Subunit structure	Homodimer. Ref.1
Subcellular location	Peroxisome. Ref.1
Tissue specificity	Expressed in leaves but not in root tissue or seedlings. Ref.1
Induction	By light. Ref.1
Sequence similarities	Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family.
