Crystal Structure of Phosphorylated C.elegans Thymidylate Synthase in Complex with dUMPCrystal Structure of Phosphorylated C.elegans Thymidylate Synthase in Complex with dUMP
Structural highlights
FunctionPublication Abstract from PubMedCrystal structure is presented of the binary complex between potassium phosphoramidate-phosphorylated recombinant C. elegans thymidylate synthase and dUMP. On each monomer a single phosphoserine residue (Ser127) was identified, instead of expected phosphohistidine. As 31P NMR studies of both the phosphorylated protein and of potassium phosphoramidate potential to phosphorylate different amino acids point to histidine as the only possible site of the modification, thermodynamically favored intermolecular phosphotransfer from histidine to serine is suggested. Crystal structure of phosphoramide-phosphorylated thymidylate synthase reveals pSer127, reflecting probably pHis to pSer phosphotransfer.,Wilk P, Jarmula A, Ruman T, Banaszak K, Rypniewski W, Ciesla J, Dowiercial A, Rode W Bioorg Chem. 2013 Nov 21;52C:44-49. doi: 10.1016/j.bioorg.2013.11.003.
