Abstract:
:Proteins of the YidC/OxaI/Alb3 family play a crucial role in the insertion, folding, and/or assembly of membrane proteins in prokaryotes and eukaryotes. Bacillus subtilis has two YidC-like proteins, denoted SpoIIIJ and YqjG. SpoIIIJ and YqjG are largely exchangeable in function, but SpoIIIJ has a unique role in sporulation, while YqjG stimulates competence development. To obtain more insight into the regions important for the sporulation specificity of SpoIIIJ, a series of SpoIIIJ/YqjG chimeras was constructed. These chimeras were tested for functionality during vegetative growth and for their ability to complement the sporulation defect of a spoIIIJ deletion strain. The data suggest an important role for the domain comprising transmembrane segment 2 (TMS2) and its flanking loops in sporulation specificity, with lesser contributions to specificity by TMS1 and TMS3.
