Accepted name: CTP-dependent riboflavin kinase
Reaction: CTP + riboflavin = CDP + FMN
Other name(s): Methanocaldococcus jannaschii Mj0056; Mj0056
Systematic name: CTP:riboflavin 5′-phosphotransferase
Comments: This archaeal enzyme differs from EC, riboflavin kinase, in using CTP as the donor nucleotide. UTP, but not ATP or GTP, can also act as a phosphate donor but it is at least an order of magnitude less efficient than CTP.
