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

cnuNucleoid-associated oriC-binding protein; Modifies the set of genes regulated by H-NS; Hha and Cnu (YdgT) increase the number of genes bound by H-NS/StpA and may also modulate the oligomerization of the H-NS/StpA-complex on DNA. The complex formed with H-NS binds to the specific 26-bp cnb site in the origin of replication oriC. Can complement, at least partially, the absence of the Hha protein in hha mutants. (71 aa)    
Predicted Functional Partners:
hns
Global DNA-binding transcriptional dual regulator H-NS; A DNA-binding protein implicated in transcriptional repression (silencing). Also involved in bacterial chromosome organization and compaction. H-NS binds tightly to AT-rich dsDNA and inhibits transcription. Binds upstream and downstream of initiating RNA polymerase, trapping it in a loop and preventing transcription. Binds to hundreds of sites, approximately half its binding sites are in non-coding DNA, which only accounts for about 10% of the genome. Many of these loci were horizontally transferred (HTG); this offers the selectiv [...]

stpA
DNA binding protein, nucleoid-associated; A DNA-binding protein that acts in a fashion similar to H-NS protein upon overexpression, represses a number of genes including the cryptic blg operon, hns, papB and the proU locus. A subset of H-NS/StpA-regulated genes also require Hha for repression; Hha and Cnu (YdgT) increases the number of genes DNA bound by H-NS/StpA and may also modulate the oligomerization of the H-NS/StpA-complex. Repression can be inhibited by dominant-negative mutants of StpA or H-NS.

ydgK
DUF2569 family inner membrane protein.

rsxA
SoxR iron-sulfur cluster reduction factor component; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane (By similarity). Required to maintain the reduced state of SoxR. Probably transfers electron from NAD(P)H to SoxR.
  
  
 0.602
blr
Beta-lactam resistance membrane protein; Component of the cell division machinery, which is probably involved in the stabilization of the divisome under certain stress conditions.
  
  
 0.602
rsxB
SoxR iron-sulfur cluster reduction factor component; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane (By similarity). Required to maintain the reduced state of SoxR. Probably transfers electron from NAD(P)H to SoxR. Belongs to the 4Fe4S bacterial-type ferredoxin family. RnfB subfamily.
  
    0.561
rsxG
SoxR iron-sulfur cluster reduction factor component; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane (By similarity). Required to maintain the reduced state of SoxR. Probably transfers electron from NAD(P)H to SoxR. Belongs to the RnfG family.

ydgJ
Putative oxidoreductase.

hha
Modulator of gene expression, with H-NS; Down-regulates hemolysin (hly) expression in complex with H- NS. Stimulates transposition events in vivo. Modifies the set of genes regulated by H-NS; Hha and Cnu (YdgT) increase the number of genes DNA bound by H-NS/StpA and may also modulate the oligomerization of the H-NS/StpA-complex. Binds DNA and influences DNA topology in response to environmental stimuli; does not however interact with DNA in the absence of H-NS. Involved in persister cell formation, acting downstream of mRNA interferase (toxin) MqsR. Decreases biofilm formation by repre [...]
