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

Predicted Functional Partners:
lpxK
Tetraacyldisaccharide 4'-kinase; Transfers the gamma-phosphate of ATP to the 4'-position of a tetraacyldisaccharide 1-phosphate intermediate (termed DS-1-P) to form tetraacyldisaccharide 1,4'-bis-phosphate (lipid IVA)
    
 0.977
msbA
Atp-binding cassette, subfamily b, bacterial msba; Involved in lipid A export and possibly also in glycerophospholipid export and for biogenesis of the outer membrane. Transmembrane domains (TMD) form a pore in the inner membrane and the ATP-binding domain (NBD) is responsible for energy generation
    
 0.880
ihfB
Integration host factor (ihf), dna-binding protein, beta subunit; One of the 2 subunits of integration host factor (IHF), a specific DNA-binding protein that functions in genetic recombination as well as in transcriptional and translational control. Has an essential role in conjugative DNA transfer (CDT), the unidirectional transfer of ssDNA plasmid from a donor to a recipient cell. It is the central mechanism by which antibiotic resistance and virulence factors are propagated in bacterial populations. Part of the relaxosome, which facilitates a site- and strand-specific cut in the ori [...]

smf
Dna recombination-mediator a family protein; Partially complements natural chromosomal DNA transformation defect of an H.influenzae dprA disruption mutant . May help load RecA onto ssDNA (By similarity)
 
  
 0.821
ppdD
Putative prepilin peptidase-dependent pilin; Not yet known
  
  
 0.813
sxy
Dna transformation protein and related proteins; Induces low levels of natural DNA uptake by inducing transcription of the competence genes (the CRP-S regulon) required for DNA transformation. Induction of the CRP-S regulon also requires Sxy- activated promoter (CRP-S), cAMP receptor protein (CRP) and cAMP . Induces CRP-S site-containing genes which are involved in genome maintenance and transcription or encoding transposases and toxin-antitoxin pairs
  
   
 0.809
ydcV
Putative spermidine/putrescine transport system permease protein; Involved in natural transformation . Probably part of the ABC transporter complex YdcSTUV. Probably responsible for the translocation of the substrate across the membrane. During natural transformation, may serve as the channel for dsDNA uptake (Probable)
  
  
 0.800
gntX
Dna utilization protein yhgh; Required for the use of extracellular DNA as a nutrient . Has been suggested to be involved in gluconate metabolism
 
  
 0.785
ruvB
Atp-dependent dna helicase, component of ruvabc resolvasome; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing
