Crystal structure of human choline kinase beta in complex with phosphorylated hemicholinium-3 and adenosine nucleotide

Template:ABSTRACT PUBMED 20299452

Function

[CHKB_HUMAN] Has a key role in phospholipid biosynthesis. Catalyzes the first step in phosphatidylethanolamine biosynthesis. Phosphorylates ethanolamine, and can also act on choline (in vitro). Has higher activity with ethanolamine. May not significantly contribute to in vivo phosphatidylcholine biosynthesis.^[1]
