GTP cyclohydrolase II; Several members of the family are bifunctional, involving both ribA and ribB function. In these cases, ribA tends to be on the C-terminal end of the protein and ribB tends to be on the N-terminal. The function of archaeal members of the family has not been demonstrated and is assigned tentatively. [Biosynthesis of cofactors, prosthetic groups, and carriers, Riboflavin, FMN, and FAD]

Riboflavin is the precursor molecule for the synthesis of the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) which are essential to cell metabolism.
