>gnl|CDD|88616 cd05153, HomoserineK_II, Homoserine Kinase, type II. Homoserine kinase is part of a larger superfamily that includes the catalytic domains of other kinases, such as the typical serine/threonine/tyrosine protein kinases (PKs), RIO kinases, actin-fragmin kinase (AFK), and phosphoinositide 3-kinase (PI3K). This subfamily is composed of unusual homoserine kinases, from a subset of bacteria, which have a PK fold. These proteins do not bear any similarity to the GHMP family homoserine kinases present in most bacteria and eukaryotes. Homoserine kinase catalyzes the transfer of the gamma-phosphoryl group from ATP to L-homoserine producing L-homoserine phosphate, an intermediate in the production of the amino acids threonine, methionine, and isoleucine..
