Hydroxylysine kinase
Template:Infobox enzyme In enzymology, a hydroxylysine kinase (Template:EC number) is an enzyme that catalyzes the chemical reaction
- GTP + 5-hydroxy-L-lysine GDP + 5-phosphonooxy-L-lysine
Thus, the two substrates of this enzyme are GTP and 5-hydroxy-L-lysine, whereas its two products are GDP and 5-phosphonooxy-L-lysine.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is GTP:5-hydroxy-L-lysine O-phosphotransferase. Other names in common use include hydroxylysine kinase (phosphorylating), and guanosine triphosphate:5-hydroxy-L-lysine O-phosphotransferase. This enzyme participates in lysine degradation.
