IUBMB Enzyme Nomenclature


Accepted name: taurine—2-oxoglutarate transaminase

Reaction: taurine + 2-oxoglutarate = 2-sulfoacetaldehyde + L-glutamate

Glossary: 2-sulfoacetaldehyde = 2-oxoethanesulfonate
taurine = 2-aminoethanesulfonate

Other name(s): taurine aminotransferase; taurine transaminase; taurine—α-ketoglutarate aminotransferase; taurine—glutamate transaminase

Systematic name: taurine:2-oxoglutarate aminotransferase

Comments: A pyridoxal-phosphate protein. Also acts on D,L-3-amino-isobutanoate, β-alanine and 3-aminopropanesulfonate. Involved in the microbial utilization of β-alanine.
