ESX-1 secretion-associated protein EspC; Required for ESX-1 function. Required for either stability or expression of EspA.

Rv3612c, (MTCY07H7B.10), len: 109 aa. Conserved hypothetical protein. Residues 58 to 81 highly similar to N-terminal part of AAK46718|MT2424 hypothetical 3.9 KDA protein from Mycobacterium tuberculosis strain CDC1551 (36 aa), FASTA scores: opt: 108, E(): 0.38, (69.25% identity in 26 aa overlap).

ESX-1 secretion-associated protein A, EspA; Required for secretion of EsxA (ESAT-6) and EsxB (CFP-10) and for virulence. Involved in translocation of bacteria from the host (human) phagolysosome to the host cytoplasm.

Rv1470, (MTV007.17), len: 124 aa. Probable trxA,thioredoxin, similar to many e.g. P12243|THI1_SYNP7 thioredoxin 1 from Synechococcus sp. (106 aa), FASTA scores: opt: 201, E(): 9.2e-08, (35.4% identity in 99 aa overlap); etc. Highly similar to downstream ORF Rv1471|trxB1 probable thioredoxin from Mycobacterium tuberculosis (123 aa), FASTA scores: opt: 402, E(): 0,(54.4% identity in 114 aa overlap). Warning: note that Rv3914|MT4033|MTV028.05|trxC can be alternatively named trxA.

Rv0188, (MTCI28.27), len: 143 aa. Probable conserved transmembrane protein, similar to T35347|4835334|CAB42956.1|AL049863|SC5H1_31 probable membrane protein from Streptomyces coelicolor (147 aa),FASTA scores: opt: 326, E(): 6.5e-15, (36.2% identity in 141 aa overlap); N-terminus of P80185|MTRC_METTH tetrahydromethanopterin S-methyltransferase subunit C from Methanobacterium thermoautotrophicum strain Marburg/DSM 2133 (266 aa), FASTA scores: opt: 125, E(): 0.033, (31.6% identity in 98 aa overlap). Also similar to Rv3635 from Mycobacterium tuberculosis.

Probable conserved lipoprotein LprQ; Generates 3->3 cross-links in peptidoglycan, catalyzing the cleavage of the mDap(3)-D-Ala(4) bond of a tetrapeptide donor stem and the formation of a bond between the carbonyl of mDap(3) of the donor stem and the side chain of mDap(3) of the acceptor stem. Is specific for donor substrates containing a stem tetrapeptide since it cannot use pentapeptide stems.

Probable carboxylesterase LipQ; Shows lipase activity. Is highly immunogenic and may play an important role in the virulence and pathogenesis of M.tuberculosis infection, by altering the balance of cytokines. Significantly down-regulates the expression level of pro- inflammatory cytokines (TNF-alpha and IFN-gamma) and up-regulates the level of anti-inflammatory cytokines such as IL-4 and IL-10 as compared to LPS stimulated macrophages. Also inhibits the expression of iNOS, TLR2 and transcription factor NF-kappa-B in LPS stimulated macrophages whereas the expression of TLR-4 remains unc [...]

Rv3839, (MTCY01A6.30c), len: 258 aa. Conserved hypothetical protein, similar in part to Q9RD78|SCF43.10cfrom hypothetical 25.8 KDA protein Streptomyces coelicolor (241 aa), FASTA scores: opt: 270,E(): 3.2e-10, (33.45% identity in 272 aa overlap); and O00320|F25451_2 hypothetical protein from Homo sapiens (Human) (339 aa), FASTA scores: opt: 126, E(): 0.77,(28.75% identity in 240 aa overlap).
