Lombricine kinase

In enzymology, a lombricine kinase (EC 2.7.3.5) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are ATP and lombricine, whereas its two products are ADP and N-phospholombricine.

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:lombricine N-phosphotransferase. This enzyme participates in glycine, serine and threonine metabolism.
