We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | [https://www.uniprot.org/uniprot/RIB7_METJA RIB7_METJA] Catalyzes an early step in riboflavin biosynthesis, the NAD(P)H-dependent reduction of the ribose side chain of 2,5-diamino-6-ribosylamino-4(3H)-pyrimidinone 5'-phosphate, yielding 2,5-diamino-6-ribitylamino-4(3H)-pyrimidinone 5'-phosphate. The beta anomer is the authentic substrate, and the alpha anomer can serve as substrate subsequent to spontaneous anomerization. NADPH and NADH function equally well as the reductants. Does not catalyze the reduction of 5-amino-6-(5-phospho-D-ribosylamino)uracil to 5-amino-6-(5-phospho-D-ribitylamino)uracil.<ref>PMID:11889103</ref> <ref>PMID:18671734</ref> | ||
