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

yxlHPutative efflux transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter. (400 aa)    
Predicted Functional Partners:
yxlG
Putative 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.
   
  
 0.980
yxlD
Putative sigma-Y antisigma factor component; Together with YxlE, is important for negative regulation of sigma Y activity, being the major negative regulator.
   
  
 0.919
yxlC
sigma-Y antisigma factor; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: 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.
