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

sigGProbable alternative RNA polymerase sigma factor SigG (RNA polymerase ECF type sigma factor); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor until released, although no anti-sigma factor is known for this protein. May be involved in host intracellular survival after infection (strains H37Rv and CDC 1551). A role in the SOS response is controversial; it has been seen in strain CDC 1551 but not i [...] (370 aa)    
Predicted Functional Partners:
Rv0181c
Conserved hypothetical protein; Putative quercetin 2,3-dioxygenase; Belongs to the pirin family.

sigL
Probable alternative RNA polymerase sigma factor SigL; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis. Over-expression of SigL induces 19-28 genes including polyketide synthases, secreted and membrane proteins. Might play a minor role in regulating SigB.
 
  
 0.824
sigD
Probable alternative RNA polymerase sigma-D factor SigD; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis.
 
  
 0.809
sigB
RNA polymerase sigma factor SigB; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. A non-essential principal sigma factor that responds to cell envelope stress and hypoxia. Controls a regulon of about 40 genes, with another 100 genes expression being altered during SDS stress and about 50 gene being altered during diamide (oxidative) stress.
  
  
 0.762
sigM
Possible alternative RNA polymerase sigma factor SigM; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor (RsaM, AC L7N5D7) until released by regulated intramembrane proteolysis (Probable). This sigma factor is required for the synthesis of surface or secreted molecules.

Rv0180c
Rv0180c, (MTCI28.20c), len: 452 aa. Probable conserved transmembrane protein, equivalent to CAC32132.1|AL583926 probable conserved membrane protein from Mycobacterium leprae (465 aa). Shows some similarity with others membrane proteins e.g. AL096849|SCI11_29 from Streptomyces coelicolor (354 aa), FASTA scores: opt: 190,E(): 0.00067, (25.9% identity in 409 aa overlap).
  
  
 0.740
sigF
Alternative RNA polymerase sigma factor SigF; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Held in an inactive form by a cognate anti-sigma factor RsbW (UsfX) until released. Increased expression decreases growth rate, and after 3 days increases the expression of 51 loci encoding 33 protein- coding genes as well as some non-coding RNA.
  
  
 0.728
sigK
Alternative RNA polymerase sigma factor SigK; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis. Sigma-K controls genes such as mpt70 and mpt83.

Rv0183
Possible lysophospholipase; Involved in the hydrolysis of exogenous host lipids during chronic infection. Catalyzes the hydrolysis of both monoacylglycerols (MAG) and diacylglycerols (DAG). It hydrolyzes 2-MAG, 1-3-MAG and MAG with short, medium and long chain fatty acids such as 1-monobutyroyl- rac-glycerol (MC4), 1-mono-octanoyl-rac-glycerol (MC8), 1-monodecanoyl- rac-glycerol (MC10), 1-monolauroyl-rac-glycerol (MC12), 1- monomyristoyl-rac-glycerol (MC14) and 1-mono-oleyl-rac-glycerol (MC18:1). Also able to hydrolyze DAG with short (DiC6) and medium (DiC10) fatty acid chains, but not [...]
