ForT酶催化5′-磷酸核糖基-1 ′-焦磷酸(PRPP)与4-氨基-1H-吡唑-3,5-二羧酸(3,5-dicarboxylic acid,3,5-dicarboxylic acid)之间形成C-C键,是链霉菌(Streptomyces kaniharaensis)合成5′-磷酸甲霉素A的关键中间体。我们报告的2.5倍分辨率的结构的ForT/PRPP复合物和定位活性位点残基的PRPP识别和催化的关键。参与生物活性C-核苷和C-核苷酸生物合成的新型C-糖苷合酶的X射线晶体结构。
The enzyme ForT catalyzes C–C bond formation between 5′-phosphoribosyl-1′-pyrophosphate (PRPP) and 4-amino-1H-pyrazole-3,5-dicarboxylate to make a key intermediate in the biosynthesis of formycin A 5′-phosphate by Streptomyces kaniharaensis. We report the 2.5 Å resolution structure of the ForT/PRPP complex and locate active site residues critical for PRPP recognition and catalysis. X-Ray crystal structure of a novel C-glycoside synthase involved in the biosynthesis of biologically active C-nucleosides and C-nucleotides.
