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:
some 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

sdiALuxr family transcriptional regulator, quorum-sensing system regulator sdia; Activates cell division by specifically increasing transcription from one of the two promoters that lie immediately upstream of the ftsQAZ gene cluster. Activates ydiV expression in response to extracellular autoinducer AI-1 (Vibrio fischeri autoinducer oxoC6) (240 aa)    
Predicted Functional Partners:
uvrY
Two-component system, narl family, invasion response regulator uvry; Member of the two-component regulatory system UvrY/BarA involved in the regulation of carbon metabolism via the CsrA/CsrB regulatory system. UvrY activates the transcription of the untranslated csrB RNA and of barA, in an autoregulatory loop. Mediates the effects of CsrA on csrB RNA by BarA-dependent and BarA-independent mechanisms

priA
Primosomal protein n' (replication factor y) (superfamily ii helicase); Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA. Is also involved in initiation of normal DNA replication in various plasmids and phages. Binds to branched DNA structures that resemble D-loops or to the primosome assembly site (PAS). Binds to DNA in two distinct modes, either de [...]

luxS
S-ribosylhomocysteine lyase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD)

aaeR
Lysr family transcriptional regulator, transcriptional activator for aaexab operon; Activates transcription of the aaeXAB operon
      
 0.732
yecC
L-cystine transport system atp-binding protein; Part of the ABC transporter complex FliY-YecC-YecS involved in L-cystine transport. The system can probably also transport L- cysteine, and it mediates accumulation of the toxic compounds L- selenaproline (SCA) and L-selenocystine (SeCys) . Probably responsible for energy coupling to the transport system (Probable)

ybeF
Putative lysr-type dna-binding transcriptional regulator ybef; Belongs to the LysR transcriptional regulatory family
  
   
 0.667
rpoS
Rna polymerase nonessential primary-like 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 master transcriptional regulator of the stationary phase and the general stress response. Controls, positively or negatively, the expression of several hundred genes, which are mainly involved in metabolism, transport, regulation and stress management

csrA
A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability, initially identified for its effects on central carbon metabolism . Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems . Binds to the 5'-UTR of mRNA to repress or activate translation; 2 binding sites on the homodimer can bridge 2 sites within target RNA (By similarity). Exerts reciprocal effects on enzymes of gluconeogenesis and glycogen biosynthesis versus [...]

hha
Haemolysin expression modulating protein; 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 [...]

rcnB
Periplasmic protein involved in nickel/cobalt export; Influences nickel and cobalt homeostasis. May act by modulating RcnA-mediated export of these ions to avoid excess efflux. Not involved in nickel import and does not bind nickel or cobalt ions directly
