CTP-dependent riboflavin kinase explained

CTP-dependent riboflavin kinase
Ec Number:	2.7.1.161

CTP-dependent riboflavin kinase (Methanocaldococcus jannaschii Mj0056, Mj0056) is an enzyme with systematic name CTP:riboflavin 5′-phosphotransferase.^[1] This enzyme catalyses the following chemical reaction

CTP + riboflavin

\rightleftharpoons CDP + FMN

This archaeal enzyme uses CTP as the donor nucleotide.
