>TIGR00506 ribB 3,4-dihydroxy-2-butanone 4-phosphate synthase; InterPro: IPR000422 3,4-Dihydroxy-2-butanone 4-phosphate is biosynthesized from ribulose 5-phosphate and serves as the biosynthetic precursor for the xylene ring of riboflavin . It is sometimes found as a bifunctional enzyme with GTP cyclohydrolase II that catalyses the first committed step in the biosynthesis of riboflavin (IPR000926 from INTERPRO). No sequences with significant homology to DHBP synthase are found in the metazoa.; GO: 0008686 34-dihydroxy-2-butanone-4-phosphate synthase activity, 0009231 riboflavin biosynthetic process.
