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

yxlDPutative sigma-Y antisigma factor component; Together with YxlE, is important for negative regulation of sigma Y activity, being the major negative regulator. (68 aa)    
Predicted Functional Partners:
yxlE
Negative regulator of sigma-Y activity; Together with YxlD is important for negative regulation of sigma Y activity.
  
  
 0.999
yxlC
sigma-Y antisigma factor; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
  
  
 0.999
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.
  
  
 0.995
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.
  
    0.967
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.
  
    0.944
rpsC
Ribosomal protein S3 (BS3); Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation; Belongs to the universal ribosomal protein uS3 family.
  
   0.942
rpsQ
Ribosomal protein S17 (BS16); One of the primary rRNA binding proteins, it binds specifically to the 5'-end of 16S ribosomal RNA.
  
   0.924
rpsO
Ribosomal protein S15 (BS18); One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it helps nucleate assembly of the platform of the 30S subunit by binding and bridging several RNA helices of the 16S rRNA.
   
   0.923
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.
   
  
 0.919
ybgB
Hypothetical protein; Evidence 5: No homology to any previously reported sequences; PubMedId: 12897008.
   
  
 0.889
