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

zurProbable zinc uptake regulation protein Zur; Global transcriptional regulator involved in zinc homeostasis. Represses the transcription of at least 32 genes, including genes involved in zinc homeostasis, by binding to promoter sequences that contain a conserved 26 bp palindrome, in the presence of zinc; Belongs to the Fur family. (130 aa)    
Predicted Functional Partners:
rpoA
DNA-directed RNA polymerase subunit alpha; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.976
smtB
Probable transcriptional regulatory protein SmtB (probably ArsR-family); Transcriptional regulator involved in zinc homeostasis. Represses the expression of the smtB-zur operon in the absence of zinc. Could act as the metal sensor that controls the expression of zur in response to zinc availability.
  
  
 0.965
furA
Ferric uptake regulation protein FurA (fur); Represses transcription of the catalase-peroxidase gene katG and its own transcription by binding to the promoter region in a redox- dependent manner; Belongs to the Fur family.
  
  
 0.900
ideR
Iron-dependent repressor and activator IdeR; Metal-dependent DNA-binding protein that controls transcription of many genes involved in iron metabolism. Acts as a repressor of siderophore biosynthesis and as a positive modulator of iron storage. Also regulates expression of transporters, proteins involved in siderophore synthesis, iron storage and transcriptional regulators.
  
  
 0.877
sigA
RNA polymerase sigma factor SigA (sigma-A); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth (Probable); Belongs to the sigma-70 factor family. RpoD/SigA subfamily.
  
 
 0.852
Rv1460
Rv1460, (MTV007.07), len: 268 aa. Probable transcriptional regulatory protein. Equivalent to Z99125|MLCL536.29c hypothetical protein from Mycobacterium leprae (254 aa), FASTA scores: opt: 1273, E(): 0, (79.6% identity in 250 aa overlap). Possible helix-turn-helix motif between aa 68 - 89. Start changed since original submission.
  
    0.847
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.
  
 
 0.835
rpoB
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
   0.834
rpoZ
DNA-directed RNA polymerase subunit omega; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
  
 
 0.832
rpoC
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
