CTP-dependent riboflavin kinase

CTP-dependent riboflavin kinase (, Methanocaldococcus jannaschii Mj0056, Mj0056) is an enzyme with systematic name CTP:riboflavin 5&prime;-phosphotransferase. This enzyme catalyses the following chemical reaction


 * CTP + riboflavin $$\rightleftharpoons$$ CDP + FMN

This archaeal enzyme uses CTP as the donor nucleotide.
