Enzyme Information

1.14.14.5
Alkanesulfonate monooxygenase.
based on mapping to UniProt P80645
An alkanesulfonate (R-CH(2)-SO(3)H) + FMNH(2) + O(2) = an aldehyde (R-CHO) + FMN + sulfite + H(2)O.
-!- The enzyme from Escherichia coli catalyzes the desulfonation of a wide range of aliphatic sulfonates (unsubstituted C(1)- to C(14)- sulfonates as well as substituted C(2)-sulfonates). -!- Does not desulfonate taurine (2-aminoethanesulfonate) or aromatic sulfonates. -!- Does not use FMN as a bound cofactor. -!- Instead, it uses reduced FMN (i.e., FMNH(2)) as a substrate. -!- FMNH(2) is provided by SsuE, the associated FMN reductase (EC 1.5.1.38).
