Abstract
A modular approach for balanced overexpression of recombinant multiprotein complexes in E. coli is described, with the prokaryotic protein secretase/insertase complex, the SecYEG-SecDFYajC-YidC holotranslocon (HTL), used as an example. This procedure has been implemented here in the ACEMBL system. The protocol details the design principles of the monocistronic or polycistronic DNA constructs, the expression and purification of functional HTL and its association with translating ribosome nascent chain (RNC) complexes into a RNC-HTL supercomplex.
