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

whiB-2WhmD; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA. (92 aa)    
Predicted Functional Partners:
sigA
RNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.

BISU_1783
Putative MerR family transcriptional regulator.
  
     0.773
BISU_0302
Hypothetical protein.
  
     0.771
BISU_1436
Hypothetical protein.
  
     0.770
BISU_1585
Preprotein translocase subunit SecG; Involved in protein export. Participates in an early event of protein translocation; Belongs to the SecG family.
  
     0.767
rpoZ
DNA-directed RNA polymerase subunit omega; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
  
     0.762
BISU_0457
Phosphoglycerate mutase.
  
     0.755
nucS
Putative nuclease of the RecB family; Cleaves both 3' and 5' ssDNA extremities of branched DNA structures; Belongs to the NucS endonuclease family.
  
     0.741
