Preprotein translocase, SecY subunit; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.

Ribosomal protein L1; Binds directly to 23S rRNA. The L1 stalk is quite mobile in the ribosome, and is involved in E site tRNA release.

Ribosomal protein L33; Similar to GB:J01677 SP:P02436 PID:147709 PID:290486 GB:U00096; identified by sequence similarity; putative; Belongs to the bacterial ribosomal protein bL33 family.

Transcription antitermination protein NusG; Participates in transcription elongation, termination and antitermination.

Ribosomal protein L10; Forms part of the ribosomal stalk, playing a central role in the interaction of the ribosome with GTP-bound translation factors. Belongs to the universal ribosomal protein uL10 family.

Preprotein translocase, SecG subunit; Involved in protein export. Participates in an early event of protein translocation; Belongs to the SecG family.

Ribosomal protein L32; Similar to GB:L42023 SP:P44368 PID:1003217 PID:1222072 PID:1204415; identified by sequence similarity; putative; Belongs to the bacterial ribosomal protein bL32 family.

Inner membrane protein, 60 kDa; 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. Aids folding of multispanning membrane proteins.

Signal recognition particle protein; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Interaction with FtsY leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individual componen [...]
