In enzymology, a taurine-2-oxoglutarate transaminase (EC 2.6.1.55) is an enzyme that catalyzes the chemical reaction
- taurine + 2-oxoglutarate sulfoacetaldehyde + L-glutamate
Thus, the two substrates of this enzyme are taurine and 2-oxoglutarate, whereas its two products are sulfoacetaldehyde and L-glutamate.
This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is taurine:2-oxoglutarate aminotransferase. Other names in common use include taurine aminotransferase, taurine transaminase, taurine-alpha-ketoglutarate aminotransferase, and taurine-glutamate transaminase. This enzyme participates in beta-alanine metabolism. It employs one cofactor, pyridoxal phosphate.
