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.

stpADNA-binding protein with chaperone activity; A DNA-binding protein that acts in a fashion similar to H-NS, repressing gene transcription. A subset of H-NS/StpA-regulated genes require auxillary proteins for repression; these auxillary proteins (Hha and other similar proteins) may also modulate oligomerization of the H-NS/StpA complex (By similarity). (133 aa)    
Predicted Functional Partners:
ydgT
Putative cytoplasmic protein; Binds to H-NS and modified the range of genes it silences; H- NS alonge silences core gene while the H-NS-Hha complex (and presumably also H-NS-YdgT) silences genes acquired by horizontal gene transfer. Plays a role silencing virulence factors in the absence of factors that induce pathogenicity (By similarity). The complex formed with H-NS binds to the specific 26-bp cnb site in the origin of replication oriC (By similarity); Belongs to the Hha/YmoA/Cnu family.

hha
Hemolysin expression modulating protein (involved in environmental regulation of virulence factors); Interacts with H-NS and in this complex might contact DNA, which could provide an additional surface for DNA binding to the H-NS- Hha complex; may not bind DNA in the absence of H-NS. In vitro improves the ability of H-NS to bind DNA under a precise set of conditions.

hns
DNA-binding protein HLP-II; Binds tightly to dsDNA. Acts as a global transcriptional regulator through its ability to bind to AT-rich DNA sequences. Binds in the minor groove of AT-rich DNA. Was found to bind 746 genes, about half of which show no change in expression in disruption experiments suggesting these sites are important for nucleoid structure. On a global level genes bound by H-NS are expressed at a lower than average level; H-NS is excluded from binding to highly transcribed genes and does not co-localize with RNA polymerase in DNA-binding studies during exponential growth i [...]

leuO
Putative LysR family transcriptional regulator; Probable activator protein in leuabcd operon. (SW:LEUO_SALTY); Belongs to the LysR transcriptional regulatory family.
      
 0.648
rpoS
Sigma S (sigma 38) factor of RNA polymerase; 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 master transcriptional regulator of the stationary phase and the general stress response.
     
 0.603
yciS
Putative inner membrane protein; Involved in the assembly of lipopolysaccharide (LPS). Belongs to the LapA family.
  
    0.598
topB
DNA topoisomerase III; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA su [...]
    
 
 0.596
yiiU
Putative cytoplasmic protein; Non-essential, abundant cell division factor that is required for proper Z-ring formation. It is recruited early to the divisome by direct interaction with FtsZ, stimulating Z-ring assembly and thereby promoting cell division earlier in the cell cycle. Its recruitment to the Z-ring requires functional FtsA or ZipA.
  
    0.585
dsbA
Periplasmic protein disulfide isomerase I; Required for disulfide bond formation in some periplasmic proteins such as PhoA or OmpA. Acts by transferring its disulfide bond to other proteins and is reduced in the process. DsbA is reoxidized by DsbB. It is required for pilus biogenesis (By similarity). Belongs to the thioredoxin family. DsbA subfamily.
  
    0.569
pssA
Phosphatidylserine synthase; CDP-diacylglycerol-serine O-phosphatidyltransferase; similar to E. coli phosphatidylserine synthase; phospholipid synthesis (AAC75638.1); Blastp hit to AAC75638.1 (452 aa), 93% identity in aa 2 - 452.
