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

Score
ybgBHypothetical protein; Evidence 5: No homology to any previously reported sequences; PubMedId: 12897008. (91 aa)    
Predicted Functional Partners:
yxlE
Negative regulator of sigma-Y activity; Together with YxlD is important for negative regulation of sigma Y activity.
     
 0.919
ybgA
Putative transcriptional regulator (GntR family); Transcriptional repressor of genes involved in glucosamine transport and utilization. Represses the expression of the gamAP operon by binding to the gamA-gamR intergenic region.
  
  
 0.902
yxlD
Putative sigma-Y antisigma factor component; Together with YxlE, is important for negative regulation of sigma Y activity, being the major negative regulator.
   
  
 0.889
sigY
RNA polymerase ECF (extracytoplasmic function)-type sigma factor (sigma-Y); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Positively regulates the expression of the sigY-yxlCDEFG operon upon nitrogen starvation. Also positively regulates ybgB.
   
  
 0.826
nagBB
Glucosamine-6-phosphate isomerase; Catalyzes the reversible isomerization-deamination of glucosamine 6-phosphate (GlcN6P) to form fructose 6-phosphate (Fru6P) and ammonium ion; Belongs to the glucosamine/galactosamine-6-phosphate isomerase family. NagB subfamily.
  
  
 0.766
yxlC
sigma-Y antisigma factor; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
   
  
 0.751
gamP
Phosphotransferase system (PTS) glucosamine-specific enzyme IICBA component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system may be involved in glucosamine transport.
  
  
 0.707
gltP
Proton/glutamate symport protein; Catalyzes the proton-dependent, binding-protein-independent transport of glutamate and aspartate; Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family.
     
 0.625
oatA
Peptidoglycan O-acetyltransferase; Evidence 1a: Function experimentally demonstrated in the studied strain; enzyme.
      
 0.483
nagR
Transcriptional regulator (GntR family); Main transcriptional repressor of genes involved in N- acetylglucosamine (GlcNAc) transport and utilization. Represses the expression of the nagAB and nagP operons by binding directly within their upstream regions. Binds to the DNA consensus sequence 5'-ATTGGTATAGACAACT-3'. Also acts as a weak repressor of mapB expression.
