Structural highlights

Function

[RIFK_METJA] Catalyzes the CTP-dependent phosphorylation of riboflavin (vitamin B2) to form flavin mononucleotide (FMN). Can also utilize UTP as the phosphate donor, although less efficiently, and it is unclear if ATP and GTP can also serve as substrates (PubMed:18245297) or not (PubMed:18073108).^{[1] [2]}
