1.5.8.1 dimethylamine + H2O + electron-transfer flavoprotein = methylamine + formaldehyde + reduced electron-transfer flavoprotein - - 1.5.8.1 dimethylamine + H2O + electron-transfer flavoprotein = methylamine + formaldehyde + reduced electron-transfer flavoprotein the enzyme functions as a 2:1e- transformase. The flavin component accepts two electrons from the substrate while the [4Fe-4S] cluster provides an output of single electrons to a flavoprotein which functions as a one-electron acceptor -, 393877
