Type I signal peptidase; Belongs to the peptidase S26 family.

Signal peptidase II LspA; This protein specifically catalyzes the removal of signal peptides from prolipoproteins; Belongs to the peptidase A8 family.

Conserved hypothetical protein YhjE.

Intramembrane zinc metallopeptidase YluC; Is responsible for Site-2 cleavage of the RsiW anti-sigma factor. This results, after a third proteolytic step catalyzed by the ClpXP protease, in the release of SigW and the transcription activation of the genes under the control of the sigma-W factor (By similarity).

Protein-export membrane protein SecDF; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. SecDF uses the proton motive force (PMF) to complete protein translocation after the ATP-dependent function of SecA; Belongs to the SecD/SecF family. SecD subfamily.

GTP-binding protein; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.

SpoIIIJ protein involved in stage III sporulation; Required for the insertion and/or proper folding and/or complex formation of integral membrane proteins into the membrane. Involved in integration of membrane proteins that insert both dependently and independently of the Sec translocase complex, as well as at least some lipoproteins; Belongs to the OXA1/ALB3/YidC family. Type 2 subfamily.

Translocase binding subunit (ATPase); Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.

RacA; Required for the formation of axial filaments and for anchoring the origin regions at the cell poles in sporulating cells, thus ensuring proper chromosome segregation in the prespore. Binds in a dispersed manner throughout the chromosome but preferentially to sites clustered in the origin portion of the chromosome, causing condensation of the chromosome and its remodeling into an elongated, anchored structure; Belongs to the RacA family.
