Human Deoxycytidine kinase dCMP, UDP, Mg ion product complex
Overview
Human deoxycytidine kinase (dCK) is involved in the, nucleotide-biosynthesis salvage pathway and has also been shown to, phosphorylate several antitumor and antiviral prodrugs. The structures of, dCK alone and the dead-end complex of dCK with substrate nucleoside and, product ADP or UDP have previously been reported; however, there is, currently no structure available for a substrate or product complex. Here, the structures of dCK complexes with the products dCMP, UDP and Mg(2+), ion, and with dAMP, UDP and Mg(2+) ion are reported. Structural, comparisons show that the product complexes with UDP and a dead-end, complex with substrate and UDP have similar active-site conformations.
About this Structure
