Protein Family Models

This is a flavin reductase family consisting of enzymes known to be flavin reductases as well as various oxidoreductase and monooxygenase components. VlmR is a flavin reductase that functions in a two-component enzyme system to provide isobutylamine N-hydroxylase with reduced flavin and may be involved in the synthesis of valanimycin [1]. SnaC is a flavin reductase that provides reduced flavin for the oxidation of pristinamycin IIB to pristinamycin IIA as catalysed by SnaA, SnaB heterodimer [2]. This flavin reductase region characterised by enzymes of the family is present in the C-terminus of potential FMN proteins from Synechocystis sp. suggesting it is a flavin reductase domain [1].

This protein is observed in operons extremely similar to that characterized in E. coli K-12 [1] responsible for the import and catabolism of pyrimidines, primarily uracil. This protein is a member of the flavin reductase family defined by PF01613. Presumably, this protein recycles the flavin of the RutA luciferase-like oxidoreductase.
