YbjI and YigB redundantly catalyze the fourth step in riboflavin synthesis; these enzymes have remained unknown for many years; other promiscuous HAD superfamily enzymes may also be able to perform this reaction (Haase, 2013). YbjI also has FMN and erythrose-4-P phosphatase activities in vitro (Kuznetsova, 2005; Kuznetsova, 2006). HAD superfamily, HAD15 family.
