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.

Protein-export membrane protein; Required for efficient translocation of secretory pre- proteins under conditions of hypersecretion but is not required for the release of mature proteins from the membrane. In the N-terminal section; belongs to the SecD/SecF family. SecD subfamily.

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.

Regulator of sigma-W protease RasP; 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. Can also cleave liberated signal peptides of PenP and Mpr, probably within in the cell membrane.

Preprotein translocase subunit; Involved in protein export. Participates in an early event of protein translocation (By similarity).

Putative dTDP glycosyl/glycerophosphate transferase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.

Putative tartrate dehydrogenase; Has multiple catalytic activities. Apart from catalyzing the oxidation of (+)-tartrate to oxaloglycolate, also converts meso- tartrate to D-glycerate and catalyzes the oxidative decarboxylation of D-malate to pyruvate; Belongs to the isocitrate and isopropylmalate dehydrogenases family.

Component of the preprotein translocase; 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.

Type I signal peptidase; Required for the cleavage of the signal sequence of TasA and TapA, which are involved in biofilm formation. Belongs to the peptidase S26B family.
