DE   methanesulfonate monooxygenase (NADH).
AN   mesylate monooxygenase.
AN   methanesulfonic acid monooxygenase.
AN   MSAMO.
AN   MSA monooxygenase.
CA   methanesulfonate + NADH + O2 = formaldehyde + H2O + NAD(+) + sulfite.
CC   -!- Methanesulfonate is the simplest of the sulfonates and is a substrate
CC       for the growth of certain methylotrophic microorganisms.
CC   -!- Compared with EC 1.14.14.5, this enzyme has a restricted substrate
CC       range that includes only the short-chain aliphatic sulfonates
CC       (methanesulfonate to butanesulfonate) and excludes all larger
CC       molecules, such as arylsulfonates.
CC   -!- The enzyme from the bacterium Methylosulfonomonas methylovora is a
CC       multicomponent system comprising an hydroxylase, a reductase (MsmD)
CC       and a ferredoxin (MsmC).
CC   -!- The hydroxylase has both large (MsmA) and small (MsmB) subunits, with
CC       each large subunit containing a Rieske-type [2Fe-2S] cluster.
CC   -!- Formerly EC 1.14.14.6.
