IUBMB Comments
The enzyme from the bacterium Bilophila wadsworthia requires pyridoxal 5'-phosphate as a cofactor, and catalyses 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 hydrolyses to sulfite and acetaldehyde. Unlike, EC 2.6.1.55, taurine---2-oxoglutarate transaminase, 2-oxoglutarate cannot serve as an acceptor for the amino group.
