Major structural reorganisation most likely accompanies the transient formation of a physiological electron transfer complex

Modelling studies coupled with experimental observations show that the transfer of electrons from trimethylamine dehydrogenase to its electron transferring flavoprotein (ETF) requires a large quaternary change in ETF. These studies describe for the first time how complex and substantial changes in quaternary structure could control interprotein electron transfer reactions, and direct electrons onto specific and intended redox partners.
