EC 3.1.3.102     
Accepted name: FMN hydrolase
Reaction: FMN + H2O = riboflavin + phosphate
Other name(s): FMN phosphatase; AtcpFHy1
Systematic name: FMN phosphohydrolase
Comments: Requires Mg2+. The enzyme, found in many isoforms purified from both bacteria and plants, is a member of the haloacid dehalogenase superfamily. Most of the isoforms have a wide substrate specificity [2], but isoforms specific for FMN also exist [3].
