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
yplPTranscriptional enhancer; May play a role in cold adaptation. (331 aa)    
Predicted Functional Partners:
sigL
RNA polymerase sigma-54 factor (sigma-L); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of the levanase operon. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for receipt of the melting signal from the remotely bound activator protein LevR for the expression of the levanase operon.
 
 
 0.982
yplQ
Putative membrane hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
    0.900
spo0F
Two-component response regulator; Key element in the phosphorelay regulating sporulation initiation. Phosphorylation of spo0B during sporulation initiation.
 
      0.695
pspA
Phage shock protein A homolog; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type h: extrachromosomal origin.
   
 
 0.666
liaH
Modulator of liaIHGFSR (yvqIHGFEC) operon expression; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type f: factor.
   
 
 0.666
ilvA
Threonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA (By similarity).
  
  
 0.620
bpsA
Promiscuous alkylpyrone synthase BpsA; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
      
 0.564
bkdR
Transcriptional regulator; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
  
   
0.504
levR
Transcriptional regulator (NifA/NtrC family); Involved in positive regulation of the levanase operon which comprises the levDEFG genes for a fructose PTS system, and sacA for levanase.
  
   
0.496
metA
Putative homoserine O-acetyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine; Belongs to the MetA family.
