General annotation (Comments)

Function

Transaminase involved in tyrosine breakdown. Converts tyrosine to p-hydroxyphenylpyruvate. Can catalyze the reverse reaction, using glutamic acid, with 2-oxoglutarate as cosubstrate (in vitro). Has no transaminase activity towards phenylalanine. Ref.3 Ref.6

Catalytic activity

L-tyrosine + 2-oxoglutarate = 4-hydroxyphenylpyruvate + L-glutamate. Ref.3 Ref.6

Cofactor

Pyridoxal phosphate.

Pathway

Amino-acid degradation; L-phenylalanine degradation; acetoacetate and fumarate from L-phenylalanine: step 2/6.

Subunit structure

Homodimer Probable.

Involvement in disease

Defects in TAT are the cause of tyrosinemia type 2 (TYRO2) [MIM:276600]; also known as Richner-Hanhart syndrome. TYRO2 is an inborn error of metabolism characterized by elevations of tyrosine in the blood and urine, and oculocutaneous manifestations. Typical features include palmoplantar keratosis, painful corneal ulcers, and mental retardation. Ref.8

Sequence similarities

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