Identification
HMDB Protein ID HMDBP00277
Secondary Accession Numbers
  • 5509
  • HMDBP03634
Name Tyrosine aminotransferase
Synonyms
  1. L-tyrosine:2-oxoglutarate aminotransferase
  2. TAT
Gene Name TAT
Protein Type Enzyme
Biological Properties
General Function Involved in 1-aminocyclopropane-1-carboxylate synthase activity
Specific 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 much lower affinity and transaminase activity towards phenylalanine.

  • Alkaptonuria
  • Cysteine and methionine metabolism
  • Disulfiram Action Pathway
  • Dopamine beta-hydroxylase deficiency
  • Hawkinsinuria
  • L-phenylalanine degradation

  • Tyrosinemia Type 3 (TYRO3)
  • Tyrosinemia Type I
  • Tyrosinemia, transient, of the newborn
  • Ubiquinone and other terpenoid-quinone biosynthesis
