ENZYME entry: EC 2.7.1.26
| Accepted Name |
|---|
| Riboflavin kinase.
|
| Alternative Name(s) |
|---|
| Flavokinase. |
| RFK. |
| Reaction catalysed |
|---|
| ATP + riboflavin <=> ADP + FMN |
| Cofactor(s) |
|---|
| Magnesium or zinc or manganese.
|
| Comment(s) |
|---|
- 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.
