Description | Riboflavin is converted into catalytically active cofactors (FAD and FMN) by the actions of riboflavin kinase ( ), which converts it into FMN, and FAD synthetase ( ), which adenylates FMN to FAD. Eukaryotes usually have two separate enzymes, while most prokaryotes have a single bifunctional protein that can carry out both catalyses, although exceptions occur in both cases. While eukaryotic monofunctional riboflavin kinase is orthologous to the bifunctional prokaryotic enzyme [ ], the monofunctional FAD synthetase differs from its prokaryotic counterpart, and is instead related to the PAPS-reductase family []. The bacterial FAD synthetase that is part of the bifunctional enzyme has remote similarity to nucleotidyl transferases and, hence, it may be involved in the adenylylation reaction of FAD synthetases [].This entry represents riboflavin kinase, which occurs as part of a bifunctional enzyme or a stand-alone enzyme. |
