STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

dosTTwo component sensor histidine kinase DosT; Interacts with the two-component regulatory system DevR/DevS (DosR/DosS) involved in onset of the dormancy response. Required for full induction of the DevR (DosR) regulon; required during early adaptation to anaerobiosis, to start induction of the DevR regulon. May act as a direct hypoxia/oxygen sensor. O(2) acts as a switch, with the Fe(2+)-O(2)-bound protein inactive in autophosphorylation. Autophosphorylates under anaerobic but not aerobic conditions, binding of NO or CO has no effect on autophosphorylation. Binds a number of gases; O(2), [...] (573 aa)    
Predicted Functional Partners:
devR
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 [...]

Rv2026c
Rv2026c, (MTV018.13c), len: 294 aa. Universal stress protein family protein, contains IPR006016 UspA domain.
 
  
 0.944
narL
Possible nitrate/nitrite response transcriptional regulatory protein NarL; Member of the two-component regulatory system NarS/NarL that regulates genes involved in aerobic nitrate metabolism. Upon phosphorylation by NarS, functions as a transcription regulator by direct binding to promoter regions of target genes together with DevR to regulate their expression during aerobic nitrate metabolism.
 
 
 0.912
hspX
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.

Rv2028c
Rv2028c, (MTV018.15c), len: 279 aa. Universal stress protein family protein, highly similar to many, contains IPR006016 UspA domain.
 
  
 0.788
acg
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.

Rv0195
Rv0195, (MTV033.03), len: 211 aa. Possible two-component response regulator, luxR family, similar to many e.g. U00008|ECOHU49_15 regulatory protein narP from Escherichia coli strain K12 (225 aa), FASTA scores: opt: 232, E(): 7.3e-09, (29.2% identity in 219 aa overlap). Start chosen by similarity. Contains probable helix-turn-helix motif at aa 166-187 (Score 1164, +3.15 SD).

Rv1747
Probable conserved transmembrane ATP-binding protein ABC transporter; Involved in the translocation of an unknown substrate across the membrane. Transmembrane domains (TMD) form a pore in the membrane and the ATP-binding domain (NBD) is responsible for energy generation. Required for virulence; In the C-terminal section; belongs to the ABC-2 integral membrane protein family.

Rv1364c
Rv1364c, (MTCY02B10.28c), len: 653 aa. Possible sigma factor regulatory protein, some similarity to RSBU_BACSU|P40399 sigma factor sibg regulation protein from Bacillus subtilis (335 aa), FASTA scores: opt: 224, E(): 2e-07, (25.8% identity in 244 aa overlap). Also known as mursiF.
