IntEnz Enzyme Nomenclature
EC 1.14.14.5

Names

Accepted name:
alkanesulfonate monooxygenase
Other names:
SsuD
sulfate starvation-induced protein 6
FMNH2-dependent aliphatic sulfonate monooxygenase
Systematic name:
alkanesulfonate, reduced-FMN:oxygen oxidoreductase

Reaction

Comments:

The enzyme from E. coli catalyses the desulfonation of a wide range of aliphatic sulfonates (unsubstituted C1- to C14-sulfonates as well as substituted C2-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., FMNH2) as a substrate. FMNH2 is provided by SsuE, the associated FMN reductase (EC 1.5.1.38).
