Preprotein translocase 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.

Protein-export membrane protein; 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.

50S ribosomal protein L34; Similar to Escherichia coli, Escherichia coli O6, Escherichia coli O157:H7, Salmonella typhimurium, Salmonella typhi, and Shigella flexneri 50S ribosomal protein L34 SWALL:RL34_ECOLI (SWALL:P02437) (46 aa) fasta scores: E(): 6.4e-17, 95.65% id in 46 aa; Belongs to the bacterial ribosomal protein bL34 family.

ATP synthase C chain; F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation.

50S ribosomal subunit protein L2; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family.

Ribonuclease P protein component; RNaseP catalyzes the removal of the 5'-leader sequence from pre-tRNA to produce the mature 5'-terminus. It can also cleave other RNA substrates such as 4.5S RNA. The protein component plays an auxiliary but essential role in vivo by binding to the 5'-leader sequence and broadening the substrate specificity of the ribozyme.

30S ribosomal protein S9; Similar to Escherichia coli, Escherichia coli O6, and Escherichia coli O157:H7 30s ribosomal protein S9 RpsI SWALL:RS9_ECOLI (SWALL:P02363) (129 aa) fasta scores: E(): 1.1e-43, 96.12% id in 129 aa, and to Salmonella typhimurium, and Salmonella typhi 30S ribosomal protein S9 RpsI SWALL:RS9_SALTY (SWALL:Q8XFX5) (129 aa) fasta scores: E(): 3.3e-44, 96.89% id in 129 aa; Belongs to the universal ribosomal protein uS9 family.

50S ribosomal protein L17; Similar to Escherichia coli, Escherichia coli O6, Escherichia coli O157:H7, and Shigella flexneri 50S ribosomal protein L17 RplQ or b3294 or c4055 or z4664 or ecs4159 or sf3326 SWALL:RL17_ECOLI (SWALL:P02416) (127 aa) fasta scores: E(): 1.2e-44, 99.16% id in 119 aa.

Preprotein translocase SecE subunit; Essential subunit of the Sec protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation; Belongs to the SecE/SEC61-gamma family.
