Riboflavin biosynthesis protein ribd
WebbThe final step on the riboflavin biosynthesis pathway is catalyzed by riboflavin synthase (EC 2.5.1.9), which converts two molecules of 6,7-dimethyl-8-ribityllumazine to riboflavin and ARP. The released ARP is recycled back into the biosynthetic pathway. Figure 1 Open in figure viewer PowerPoint Riboflavin biosynthesis pathway in plants. Webb1 mars 1997 · The ribG gene at the 5' end of the riboflavin operon of Bacillus subtilis and a reading frame at 442 kb on the Escherichia coli chromosome (subsequently designated ribD) show similarity with deoxycytidylate deaminase and with the RIB7 gene of Saccharomyces cerevisiae.

WebbPhosphotransferase from carrot is shown to catalyze the phosphorylation of 6,7-dimethyl-8-ribityllumazine specifically at position 5′ of the ribityl side chain. The lumazine 5′-phosphate is neither a substrate nor an inhibitor of riboflavin synthase from Bacillus subtilis and Escherichia coli . It follows that the obligatory product of riboflavin synthase … WebbThere are two ways bacteria can obtain riboflavin, one of them being the riboflavin biosynthetic pathway (RBP) and the other the riboflavin importer systems. The RBP uses guanosine-5-triphosphate (GTP) and ribulose 5-phos- phate as precursors for the biosynthesis of riboflavin.
