50S ribosomal protein L19 RplS; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.

Probable GTP-binding protein LepA (GTP-binding elongation factor); Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.

Rv0519c, (MTCY20G10.09c), len: 300 aa. Possible conserved membrane protein, with hydrophobic region near N-terminus. Could be a lipase. Similar to Rv0774c|MTCY369.19c|A70708 from Mycobacterium tuberculosis (312 aa), FASTA scores: opt: 1092, E(): 0, (57.9% identity in 299 aa overlap). Contains PS00120 Lipases, serine active site.

Rv2253, (MTV022.03), len: 167 aa. Possible secreted protein; has potential N-terminal signal peptide. Predicted to be an outer membrane protein (See Song et al., 2008).

Conserved protein; Rv3705c, (MTV025.053c), len: 214 aa. Conserved protein, equivalent to Q9CB80|ML2320 hypothetical protein from Mycobacterium leprae (215 aa) FASTA scores: opt: 1145,E(): 5.9e-68, (79.45% identity in 214 aa overlap). Some similarity to the C-terminal end of Q11053|PKNH_MYCTU|Rv1266c|MT1304|MTCY50.16 probable serine/threonine-protein from Mycobacterium tuberculosis (626 aa), FASTA scores: opt: 175, E(): 0.0005, (24.9% identity in 201 aa overlap); and to the N-terminal end of P23903|E13B_BACCI|GLCA glucan endo-1,3-beta-glucosidase A1 precursor from Bacillus circulans (68 [...]

Conserved protein; Rv2901c, (MTCY274.32c), len: 101 aa. Conserved protein, very equivalent to O33023|ML1610|MLCB250.41 hypothetical 12.3 KDA protein from Mycobacterium leprae (101 aa), FASTA scores: opt: 658, E(): 2.6e-43, (99.0% identity in 101 aa overlap). Also highly similar to O69889|SC2E1.18 hypothetical protein from Streptomyces coelicolor and Streptomyces lividans (102 aa), FASTA scores: opt: 515, E(): 2.2e-32, (75.0% identity in 100 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Probable lipoprotein signal peptidase LspA; This protein specifically catalyzes the removal of signal peptides from prolipoproteins; Belongs to the peptidase A8 family.

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 [...]
