FunctionTHYX_THEMA Catalyzes the formation of dTMP and tetrahydrofolate from dUMP and methylenetetrahydrofolate. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedLike thymidylate synthase (TS) in eukaryotes, the thymidylate synthase-complementing proteins (TSCPs) are mandatory for cell survival of many prokaryotes in the absence of external sources of thymidylate. Details of the mechanism of this novel family of enzymes are unknown. Here, we report the structural and functional analysis of a TSCP from Thermotoga maritima and its complexes with substrate, analogs, and cofactor. The structures presented here provide a basis for rationalizing the TSCP catalysis and reveal the possibility of the design of an inhibitor. We have identified a new helix-loop-strand FAD binding motif characteristic of the enzymes in the TSCP family. The presence of a hydrophobic core with residues conserved among the TSCP family suggests a common overall fold. Functional analysis of substrate and cofactor complex structures of a thymidylate synthase-complementing protein.,Mathews II, Deacon AM, Canaves JM, McMullan D, Lesley SA, Agarwalla S, Kuhn P Structure. 2003 Jun;11(6):677-90.
