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

yxlGPutative ABC-transporter (permease); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter. (258 aa)    
Predicted Functional Partners:
yxlF
Putative ABC transporter component (ATP-binding protein); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
 
 
 0.989
yxlE
Negative regulator of sigma-Y activity; Together with YxlD is important for negative regulation of sigma Y activity.
 
    0.986
yxlH
Putative efflux transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
   
  
 0.980
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.
 
    0.948
yxlD
Putative sigma-Y antisigma factor component; Together with YxlE, is important for negative regulation of sigma Y activity, being the major negative regulator.
  
    0.944
yxlC
sigma-Y antisigma factor; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
  
    0.921
antE
Hypothetical protein; Evidence 5: No homology to any previously reported sequences; PubMedId: 9864351.
      
 0.757
ypbS
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
      
 0.750
yfhS
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 10463184.
      
 0.749
yqfU
Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
