CRYSTAL STRUCTURE OF HUMAN CHOLINE KINASE ALPHA-2 IN COMPLEX WITH ADP
|
OverviewOverview
Choline kinase, responsible for the phosphorylation of choline to, phosphocholine as the first step of the CDP-choline pathway for the, biosynthesis of phosphatidylcholine, has been recognized as a new target, for anticancer therapy. Crystal structures of human choline kinase in its, apo, ADP and phosphocholine-bound complexes, respectively, reveal the, molecular details of the substrate binding sites. ATP binds in a cavity, where residues from both the N and C-terminal lobes contribute to form a, cleft, while the choline-binding site constitutes a deep hydrophobic, groove in the C-terminal domain with a rim composed of negatively charged, residues. Upon binding of choline, the enzyme undergoes conformational, changes independently affecting the N-terminal domain and the ATP-binding, ... [(full description)]
