| Research Abstract |
Protein integration is an essential process in all living cells. In this study, we determined the crystal structure of YidC, an membrane protein insertase, at 2.4 A resolution and showed by structural-based functional analyses that YidC provides a hydrophilic cavity for membrane protein insertion. Finally, we proposed a new model of the molecular mechanism of YidC-mediated protein insertion into the cytoplasmic membrane.
