Enzymes

General function:
Involved in alkanesulfonate monooxygenase activity
Specific function:
Involved in desulfonation of aliphatic sulfonates. Catalyzes the conversion of pentanesulfonic acid to sulfite and pentaldehyde and is able to desulfonate a wide range of sulfonated substrates including C-2 to C-10 unsubstituted linear alkanesulfonates, substituted ethanesulfonic acids and sulfonated buffers
