SecY subunit of preprotein translocase; 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.

Putative secreted protein; The SecYEG-SecDF-YajC-YidC holo-translocon (HTL) protein secretase/insertase is a supercomplex required for protein secretion, insertion of proteins into membranes, and assembly of membrane protein complexes. While the SecYEG complex is essential for assembly of a number of proteins and complexes, the SecDF-YajC-YidC subcomplex facilitates these functions.

SecE preprotein translocase; Essential subunit of the Sec protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation.

Putative conserved membrane protein; 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 (By similarity).

Putative protein-export membrane protein; Involved in protein export. Participates in an early event of protein translocation (By similarity); Belongs to the SecG family.

Putative lipoprotein; Similar to M. tuberculosis Rv2585c, hypothetical protein, SW:YP85_MYCTU (Q50636) (557 aa); Fasta score E(): 0, 78.9% identity in 546 aa overlap. Previously sequenced as SW:YP85_MYCLE (Q49646) (426 aa); Fasta score E(): 0, 98.8% identity in 332 aa overlap. Contains a probable N-terminal signal sequence. Contains PS00013 Prokaryotic membrane lipoprotein lipid attachment site.

Putative preprotein translocase subunit; 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.

Putative GTP pyrophosphokinase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes the formation of pppGpp which is then hydrolyzed to form ppGpp (By similarity).

phenylalanyl-tRNA synthase [beta] subunit; Highly similar to many phenylalanyl-tRNA synthetase beta chains including: Escherichia coli SW:SYFB_ECOLI (P07395) (795 aa); Fasta score E(): 0, 31.0% identity in 851 aa overlap and Mycobacterium tuberculosis RV1649 SW:SYFB_MYCTU (P94985) (831 aa); Fasta score E(): 0, 79.6% identity in 834 aa overlap.
