DCMP HYDROXYMETHYLASE FROM T4
Overview
Bacteriophage T4 deoxycytidylate hydroxymethylase (EC 2.1.2.8), a, homodimer of 246-residue subunits, catalyzes hydroxymethylation of the, cytosine base in deoxycytidylate (dCMP) to produce 5-hydroxymethyl-dCMP., It forms part of a phage DNA protection system and appears to function in, vivo as a component of a multienzyme complex called deoxyribonucleoside, triphosphate (dNTP) synthetase. We have determined its crystal structure, in the presence of the substrate dCMP at 1.6 A resolution. The structure, reveals a subunit fold and a dimerization pattern in common with, thymidylate synthases, despite low (approximately 20%) sequence identity., Among the residues that form the dCMP binding site, those interacting with, the sugar and phosphate are arranged in a configuration similar to the, ...
