ENZYME entry: EC 2.6.1.77

Accepted Name
Taurine--pyruvate aminotransferase.
Reaction catalysed
Taurine + pyruvate <=> L-alanine + 2-sulfoacetaldehyde
Cofactor(s)
Pyridoxal 5'-phosphate.
Comment(s)
  • The enzyme from Bilophila wadsworthia catalyzes a reversible reaction that starts an anaerobic taurine degradation pathway.
  • beta-alanine is also a significant amino group donor.
  • The enzyme from the bacterium Pseudomonas denitrificans PD1222 can also use hypotaurine, producing 2-sulfinoacetaldehyde, which spontaneously hydrolyzes to sulfite and acetaldehyde.
  • Unlike EC 2.6.1.55, 2-oxoglutarate cannot serve as an acceptor for the amino group.
