ENZYME entry: EC 1.14.14.5

Accepted Name
Alkanesulfonate monooxygenase.
Alternative Name(s)
FMNH(2)-dependent aliphatic sulfonate monooxygenase.
Sulfate starvation-induced protein 6.
Reaction catalysed
An alkanesufonate (R-CH(2)-SO(3)H) + FMNH(2) + O(2) <=> an aldehyde (R-CHO) + FMN + sulfite + H(2)O
Comment(s)
  • 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).
