	2.6.1.77
Description	Taurine--pyruvate aminotransferase.
Alternative names	taurine + pyruvate = L-alanine + 2-sulfoacetaldehyde
Cofactor	Pyridoxal-phosphate.
Comments	-!- The enzyme from Bilophila wadsworthia is reversible, and catalyzes the first step of anaerobic taurine degradation. -!- Hypotaurine (i.e. 2-aminoethanesulfinate) and beta-alanine are also significant donors of an amino group. -!- Unlike, EC 2.6.1.55, 2-oxoglutarate is not an acceptor of amino groups.
Organisms	-Bacteria
Family	2.6.1.77 (6)
