Fig. 2From: Biosynthesis of C-nucleoside antibiotics in actinobacteria: recent advances and future developmentsMechanism of C–C bond formation for related antibiotics. a The YeiC phosphorylates pseudouridine to produce PsiMP, and then hydrolyzed to uracil and ribose 5-P by YeiN. b β-RFAPS catalyzes the condensation of p-aminobenzoate (pABA) and PRPP to β-RFAP. c The pseudouridine is generated from isomerization of uridine-tRNA, catalyzed by TruD. YeiC, pseudouridine kinase; ribose 5-P, ribose-5′-Phosphate; β-RFAPS, β-RFAP synthaseBack to article page
