Substrate-induced assembly and functional mechanism of the bacterial membrane protein insertase SecYEG-YidC The universally conserved Sec translocon and the YidC/Oxa1-type insertases mediate biogenesis of alpha-helical membrane proteins, but the molecular basis of their cooperation has remained disputed over decades. A recent discovery of a multi-subunit insertase in eukaryotes has raised the question about the architecture of the putative bacterial ortholog SecYEG-YidC and its functional mechanism. Here, we combine cryogenic electron microscopy with cell-free protein synthesis in nanodiscs to visualize biogenesis of the polytopic membrane protein NuoK, the subunit K of NADH-quinone oxidoreductase, that requires both SecYEG and YidC for insertion. We demonstrate that YidC is recruited to the back of the translocon at the late stage of the substrate insertion, in resemblance to the eukaryotic system, and in vivo experiments indicate that the complex assembly is vital for the cells. The nascent chain does not utilize the lateral gate of SecYEG, but enters the lipid membrane at the SecYE-YidC interface, with YidC being the primary insertase. SecYEG-YidC complex promotes folding of the nascent helices at the interface prior their insertion, so the examined cellular pathway follows the fundamental thermodynamic principles of membrane protein folding. Our data provide the first detailed insight on the elusive insertase machinery in the physiologically relevant environment, highlight the importance of the nascent chain for its assembly, and prove the evolutionary conservation of the gate-independent insertion route. ### Competing Interest Statement The authors have declared no competing interest.
