1.14.14.34

Accepted name:

methanesulfonate monooxygenase (FMNH₂)

Reaction:

methanesulfonate + FMNH₂ + O₂ = formaldehyde + FMN + sulfite + H₂O

Glossary:

methanesulfonate = CH₃-SO₃^-
formaldehyde = H-CHO

Other name(s):

msuD (gene name); ssuD (gene name)

Systematic name:

methanesulfonate,FMNH₂:oxygen oxidoreductase

Comments:

The enzyme, characterized from Pseudomonas strains, allows the organisms to utilize methanesulfonate as their sulfur source. It acts in combination with a dedicated NADH-dependent FMN reductase (EC 1.5.1.42), which provides it with reduced FMN. cf. EC 1.14.13.111, methanesulfonate monooxygenase (NADH).
