- Riboflavin kinase
In
enzymology , a riboflavin kinase (EC number|2.7.1.26) is anenzyme that catalyzes thechemical reaction :ATP + riboflavin ADP + FMN
Thus, the two substrates of this enzyme are ATP and
riboflavin , whereas its two products are ADP and FMN.This enzyme belongs to the family of
transferase s, specifically those transferring phosphorus-containing groups (phosphotransferase s) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:riboflavin 5'-phosphotransferase. This enzyme is also called flavokinase. This enzyme participates inriboflavin metabolism . However, archaeal riboflavin kinases are supposedly generally utilizingCTP rather than ATP as the donor nucleotide.tructural studies
