In Pathway: two-component alkanesulfonate monooxygenase

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Instance reactions:
1-butanesulfonate + FMNH2 + oxygen → butanal + sulfite + FMN + H2O + 2 H+ (1.14.14.5)

isethionate + FMNH2 + oxygen → glycolaldehyde + sulfite + FMN + H2O + 2 H+ (1.14.14.5)

3-(N-morpholino)propanesulfonate + FMNH2 + oxygen → 3-(N-morpholino)propanal + sulfite + FMN + H2O + 2 H+ (1.14.14.5)

Enzyme Commission Primary Name: alkanesulfonate monooxygenase

Enzyme Commission Synonyms: SsuD, sulfate starvation-induced protein 6, alkanesulfonate,reduced-FMN:oxygen oxidoreductase

Enzyme Commission Summary:
The enzyme from Escherichia 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).
