Description Tyrosine aminotransferase
Alternative names Tyrosine transaminase;
Catalyzed reaction L-tyrosine + 2-oxoglutarate = 4-hydroxyphenylpyruvate + L-glutamate.
Cofactor Pyridoxal-phosphate.
Comments -!- L-phenylalanine can act instead of L-tyrosine.
-!- The mitochondrial enzyme may be identical with EC
-!- The three isoenzymic forms are interconverted by EC
May overlap with
Diseases Tyrosinemia II (Richner-Hanhart syndrome)
Prosite PROSITE; PDOC00098;
PDB 1BW0; 4IX8;
Organisms -Eubacteria -Plants -Fungi -Metazoa -Human
