Reaction: trimethylamine + H2O + electron-transfer flavoprotein = dimethylamine + formaldehyde + reduced electron-transferring flavoprotein
Systematic name: trimethylamine:electron-transferring flavoprotein oxidoreductase (demethylating)
Comments: A number of alkyl-substituted derivatives of trimethylamine can also act as electron donors; phenazine methosulfate and 2,6-dichloroindophenol can act as electron acceptors. Contains FAD and a [4Fe-4S] cluster.
