A single mutation within a flavoprotein is capable of switching the catalytic activity of a dehalogenase into a nitroreductase This change in function correlates with a destabilization of the one electron reduced flavin semiquinone that is differentially expressed in the nitro FMN reductase superfamily during redox cycling The diversity of function within such a superfamily therefore has the
