Conserved protein; Rv2030c, (MTV018.17c), len: 681 aa. Conserved protein. Predicted possible vaccine candidate (See Zvi et al., 2008).

Conserved protein Acg; Rv2032, (MTV018.19), len: 331 aa. Acg (for acr-coregulated gene), conserved protein possibly member of a superfamily of classical nitroreductases (see Purkayastha et al., 2002), similar to Rv3127 and Rv3131. Predicted possible vaccine candidate (See Zvi et al., 2008); Belongs to the nitroreductase family.

Heat shock protein HspX (alpha-crystallin homolog) (14 kDa antigen) (HSP16.3); Acts as a chaperone, as it has a significant ability to suppress the thermal denaturation of alcohol dehydrogenase. Cells overexpressing this gene grow more slowly than wild-type cells, and are less susceptible to autolysis following saturation of the culture in vitro, suggesting this protein may slow down the growth rate of M.tuberculosis in culture and by extension during macrophage infection. Belongs to the small heat shock protein (HSP20) family.

Two component transcriptional regulatory protein DevR (probably LuxR/UhpA-family); Member of the two-component regulatory system DevR/DevS (also called DosR/DosS) involved in onset of the dormancy response. Regulates an approximately 48-member regulon. When phosphorylated binds and activates the promoter of DevR regulon genes in response to hypoxia. The presence of target DNA increases stability of phospho-DevR in vitro. Activates its own transcription under hypoxic but not aerobic conditions, probably binds as a dimer to tandem binding sites within the devR and hspX promoters. Accepts [...]

Rv1997, (MTCY39.22c, MTCY39.21c), len: 905 aa.

Rv2625c, (MTCY01A10.07), len: 393 aa.

Two component sensor histidine kinase DevS; Member of the two-component regulatory system DevR/DevS (DosR/DosS) involved in onset of the dormancy response. Regulates an approximately 48-member regulon. Required for full induction of the DevR (DosR) regulon; acts later than DosT to positively regulate expression of the DevR regulon during adaptation to anaerobiosis. Characterized as an oxygen sensor; O(2) acts as a switch, with O(2)-bound Fe(2+) protein inactive in autophosphorylation. Has also been suggested to act as a redox sensor, or perhaps as a dual oxygen/redox sensor. Autophosph [...]
