In enzymology, a taurocyamine kinase (EC 2.7.3.4) is an enzyme that catalyzes the chemical reaction
- ATP + taurocyamine
ADP + N-phosphotaurocyamine
Thus, the two substrates of this enzyme are ATP and taurocyamine, whereas its two products are ADP and N-phosphotaurocyamine.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a nitrogenous group as acceptor. The systematic name of this enzyme class is ATP:taurocyamine N-phosphotransferase. Other names in common use include taurocyamine phosphotransferase, and ATP:taurocyamine phosphotransferase. This enzyme participates in taurine and hypotaurine metabolism.
