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

Rv2240cUnknown protein; Rv2240c, (MTCY427.21c), len: 196 aa. Unknown protein. Start changed since first submission (-69 aa). (196 aa)    
Predicted Functional Partners:
Rv2239c
Rv2239c, (MTCY427.20c), len: 158 aa. Conserved hypothetical protein, similar to conserved hypothetical proteins from Mycobacterium leprae (ML1649, 140 aa) and Streptomyces coelicolor A3(2) (SCC8A.28c, 159 aa). Equivalent to ML1649 conserved hypothetical protein (140 aa). FASTA scores: ML1649 conserved hypothetical protein (140 aa) opt: 846, E(): 6.5e-45; 86.429% identity in 140 aa overlap (tr|O69479|O69479 hypothetical 15.2 KDA protein (140 aa); and opt: 447, E(): 1.2e-21; 50.355% identity (51.825% ungapped) in 141 aa overlap. Similarity with ML1649 suggests alternative start at 251198.

ahpE
Probable peroxiredoxin AhpE; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. May represent an important antioxidant defense against cytotoxic peroxides, especially peroxynitrite, which can be formed by activated macrophages during infection. Belongs to the peroxiredoxin family. AhpE subfamily.

rsfB
Anti-anti-sigma factor RsfB (anti-sigma factor antagonist) (regulator of sigma F B); Positive regulator of sigma-F (SigF) activity. Binds to anti- sigma-F factor RsbW (UsfX) preventing its binding to SigF, thus activating transcription.
   
  
 0.810
obg
Probable GTP1/Obg-family GTP-binding protein Obg; An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate. Plays a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control (By similarity). GTPase activity is not inhibited by ATP or GDP. Overexpression decreases cell growth starting in late log phase and continuing into stationary phase ; Belongs to the TRAFAC class OBG-HflX-like GTPase superfa [...]

Rv2235
Rv2235, (MTCY427.16), len: 271 aa. Probable conserved transmembrane protein (see Miller & Shinnick 2001); hydrophobic regions near N- and C-terminus. Similar to conserved membrane proteins in other Actinomycetes. Equivalent to Mycobacterium leprae. ML1644 (270 aa). FASTA scores: opt: 1357, E(): 1.2e-72; 74.170% identity in 271 aa overlap T44717|3150235|CAA19213.1|AL023635 13093419|CAC30595.1|AL583922. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al.,2004).

Rv0365c
Conserved protein; Rv0365c, (MTCY13E10.27c), len: 376 aa (start uncertain). Conserved protein (see citation below), very similar to G388212|CAA35191.1, a truncated ORF immediately upstream of the Corynebacterium glutamicum fda gene encoding fructose-1,6-biphosphate aldolase (304 aa), FASTA scores: E(): 7.1e-19, (42.2% identity in 296 aa overlap).
   
  
 0.801
aceE
Pyruvate dehydrogenase E1 component; Component of the pyruvate dehydrogenase (PDH) complex, that catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). AceE has reductase activity with pyruvate but does not react with 2- oxoglutarate.
  
    0.740
rsfA
Anti-anti-sigma factor RsfA (anti-sigma factor antagonist) (regulator of sigma F A); Positive, redox-sensitive regulator of sigma-F (SigF) activity. When reduced binds to anti-sigma-F factor RsbW (UsfX) preventing its binding to SigF, thus activating transcription. Belongs to the anti-sigma-factor antagonist family.
   
  
 0.722
rsbW
Anti-sigma factor RsbW (sigma negative effector); A cognate anti-sigma factor for alternative sigma factor SigF. Alternative sigma factors are held in an inactive form by an anti-sigma factor. Binds ATP and GTP, may hydrolyze both.
