General annotation (Comments)

Function	Catalyzes the desulfonation of aliphatic sulfonates. Shows highest activity with methanesulfonate. Ref.1
Catalytic activity	An alkanesufonate (R-CH(2)-SO3H) + FMNH2 + O2 = an aldehyde (R-CHO) + FMN + sulfite + H2O. HAMAP MF_01229
Induction	Repressed by sulfate, cysteine, or thiocyanate. HAMAP MF_01229
Miscellaneous	FMNH2 which is absolutely required for this enzymatic reaction, is provided by MsuE. HAMAP MF_01229
Sequence similarities	Belongs to the SsuD family.
