Biosynthesis takes place in bacteria, fungi and plants, but not animals. The biosynthetic precursors to riboflavin are ribulose 5-phosphate and guanosine triphosphate. The former is converted to L-3,4-dihydroxy-2-butanone-4-phosphate while the latter is transformed in a series of reactions that lead to 5-amino-6-(D-ribitylamino)uracil. These two compounds are then the substrates … WebbRiboflavin (vitamin B (2)) is the precursor of the flavin coenzymes flavin mononucleotide and flavin adenine dinucleotide. In Escherichia coli and other bacteria, sequential deamination and reduction steps in riboflavin biosynthesis are catalyzed by RibD, a bifunctional protein with distinct pyrimidine deaminase and reductase domains.
