Mutated TMADH

After expressing, it'll produce trimethylamine dehydrogenase (TMADH (EC 1.5.99.7)). The enzyme TMADH is an iron–sulfur flavoprotein which catalyses the oxidative demethylation of trimethylamine (TMA) to dimethylamine and formaldehyde:
(CH3)3N + H2O → (CH3)2NH + CH2O +2H+ + 2e-.

But its sequence is different from wide type. Amino acid 344 is mutated from Val to Cys. The V334C mutant is designed for wiring from the protein close to the 4Fe–4S centre, but the initial electron transfer is activated on the opposite side of the protein, close to the FMN prosthetic group, by substrate (trimethylamine) binding at the active site.

Metabolic Pathway

This enzyme is a complex iron-sulfur flavoprotein that transfers electrons to the soluble flavoprotein known as electron transferring flavoprotein.[1] It couldn't work extracellular isolated.
