Enzyme Information
| 2.7.1.26 | Riboflavin kinase. based on mapping to UniProt Q969G6 ATP + riboflavin = ADP + FMN. -!- The cofactors FMN and FAD participate in numerous processes in all organisms, including mitochondrial electron transport, photosynthesis, fatty-acid oxidation, and metabolism of vitamin B(6), vitamin B12 and folates. -!- While monofunctional riboflavin kinase is found in eukaryotes, some bacteria have a bifunctional enzyme that exhibits both this activity and that of EC 2.7.7.2. -!- In Bacillus subtilis, ATP can be replaced by other phosphate donors but with decreasing enzyme activity in the order ATP > dATP > CTP > UTP. |
