Conserved protein; Rv3850, (MTCY01A6.18c), len: 218 aa. Conserved protein, equivalent to Q9CDD0|ML0068 hypothetical protein from Mycobacterium leprae (238 aa) FASTA scores: opt: 1071,E(): 7.2e-55, (78.35% identity in 217 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Isocitrate lyase Icl (isocitrase) (isocitratase); Involved in the persistence and virulence of M.tuberculosis. Catalyzes the reversible formation of succinate and glyoxylate from isocitrate, a key step of the glyoxylate cycle, which operates as an anaplerotic route for replenishing the tricarboxylic acid cycle during growth on fatty acid substrates. It could also catalyze the formation of pyruvate and succinate from 2-methylisocitrate, a key step in the methylcitrate cycle (propionate degradation route) (By similarity).

Possible membrane protein; Rv3851, (MTCY01A6.17c), len: 94 aa. Possible membrane protein.

ESX-1 transcriptional regulatory protein EspR; Virulence regulator that has both architectural and regulatory roles. Impacts cell wall functions and pathogenesis through regulation of multiple genes, including the espACD operon, which is a key ESX-1 component. Influences target gene expression positively or negatively, depending on its binding position relative to the genes it controls. Acts by binding directly to the DNA. May play a central role in regulating virulence gene expression.

Rv3211, (MTCY07D11.15c), len: 527 aa. Probable rhlE,ATP-dependent RNA helicase, equivalent (but shorter 22 aa) to Q9CCH3|RHLE|ML0811 putative ATP-dependent RNA helicase from Mycobacterium leprae (544 aa), FASTA scores: opt: 2497, E(): 8.7e-131, (74.75% identity in 531 aa overlap). Also highly similar to other RNA helicases e.g. Q9FBJ2|SCP8.29c from Streptomyces coelicolor (879 aa),FASTA scores: opt: 1458, E(): 3.6e-73, (52.5% identity in 522 aa overlap); Q9DF36 from Xenopus laevis (African clawed frog) (800 aa), FASTA scores: opt: 792, E(): 2.3e-36,(37.15% identity in 385 aa overlap); [...]

Probable cold-shock DeaD-box protein A homolog DeaD (ATP-dependent RNA helicase dead homolog); DEAD-box RNA helicase involved in various cellular processes at low temperature, including ribosome biogenesis, mRNA degradation and translation initiation.

Superoxide dismutase [FE] SodA; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems.

Possible large-conductance ion mechanosensitive channel MscL; Channel that opens in response to stretch forces in the membrane lipid bilayer. The force required to trigger channel opening depends on the nature of the membrane lipids; the presence of phosphatidylinositol enhances mechanosensitivity of the channel. May participate in the regulation of osmotic pressure changes within the cell.

Rv0688, (MTCY210.05), len: 406 aa. Putative ferredoxin reductase, highly similar to others e.g. BAB55881.1|AB054975 ferredoxin reductase from Terrabacter sp. DBF63 (410 aa); CAC04223.1|AL391515 putative ferredoxin reductase from Streptomyces coelicolor (420 aa); PPU24215_8|Q51973 P-cumate dioxygenase ferredoxin reductase subunit from Pseudomonas putida (402 aa), FASTA scores: opt: 738, E(): 0, (38.8% identity in 330 aa overlap); etc. Also similar to Rv0253 and Rv1869c from Mycobacterium tuberculosis. Could belong to the bacterial type ferredoxin family.
