TorD prepares the molybdoenzyme TorA for MGD cofactor insertion, independent of signal peptide binding. torD, dmsD and ycdY are paralogs. Overexpressed YdcY and DmsD interfere with apoTorA maturation by TorD, independent of the TorA signal peptide (Ilbert, 2004). Bifunctional TorD acts in MGD insertion and TorA export proof-reading, a step that insures only mature protein is exported.[4]
