In enzymology a homoserine kinase (EC 2.7.1.39) is an enzyme that catalyzes the chemical reactionATP + L-homoserine ADP + O-phospho-L-homoserineThus the two substrates of this enzyme are ATP and L-homoserine whereas its two products are ADP and O-phospho-L-homoserine.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor.
