EC 1.5.8.2 - Trimethylamine dehydrogenase

IntEnz Enzyme Nomenclature
EC 1.5.8.2

Names

Reaction

• trimethylamine + H2O + electron-transferring flavoprotein = dimethylamine + formaldehyde + reduced electron-transferring flavoprotein

Cofactors

• FMN
• iron-sulfur

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.
