FMN adenylyltransferase

In enzymology, a FMN adenylyltransferase is an enzyme that catalyzes the chemical reaction


 * ATP + FMN $$\rightleftharpoons$$ diphosphate + FAD

Thus, the two substrates of this enzyme are ATP and FMN, whereas its two products are diphosphate and FAD.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is ATP:FMN adenylyltransferase. Other names in common use include FAD pyrophosphorylase, riboflavin mononucleotide adenylyltransferase, adenosine triphosphate-riboflavin mononucleotide transadenylase, adenosine triphosphate-riboflavine mononucleotide transadenylase, FAD synthetase, riboflavin adenine dinucleotide pyrophosphorylase, and riboflavine. This enzyme participates in riboflavin metabolism.
