Probable conserved membrane protein secretion factor YajC; 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.

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

Probable preprotein translocase SecE1; Essential subunit of the Sec protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation.

Probable preprotein translocase SecY; 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. Belongs to t [...]

Probable conserved transmembrane 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).

Rv1650, (MTCY06H11.15), len: 831 aa. Probable pheT,Phenylalanyl-tRNA synthetase beta chain, similar to several e.g. SYFB_ECOLI|P07395 from Escherichia coli (795 aa),FASTA scores: opt: 995, E(): 0, (31.8% identity in 847 aa overlap). Belongs to the phenylalanyl-tRNA synthetase beta chain family - subfamily 1.

Probable preprotein translocase SecA1 1 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 precursor proteins, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane (By similarity).

Possible conserved lipoprotein; Rv2585c, (MT2662, MTCY227.16), len: 557 aa. Possible conserved lipoprotein precursor, possibly attached to the membrane by a lipid anchor and substrate-binding protein involved in transport, equivalent to Q49646|YP85_MYCLE|ML0489|MLCB1259.07|B1177_C2_197 hypothetical lipoprotein precursor from Mycobacterium leprae (555 aa), FASTA scores: opt: 2812, E(): 9.8e-158,(78.95% identity in 546 aa overlap); and C-terminus highly similar to C-terminus of Q49638|DCIAE|B1177_C1_166 DCIAE protein from Mycobacterium leprae (344 aa), FASTA scores: opt: 1177, E(): 7.4e- [...]

Probable signal recognition particle protein Ffh (fifty-four homolog) (SRP 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 (By similarity). Shows GTPase activity; Belongs to the GTP-binding SRP family. SRP54 subfamily.
