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

prtVProtease; Metalloprotease that exhibits a cytotoxic effect leading to cell death. In host tissues, it could play a role in pathogenesis by modulating the stability of the extracellular matrix components such as fibronectin and fibrinogen. Also able to cleave plasminogen. (918 aa)    
Predicted Functional Partners:
VC_1952
Chitinase; Similar to GP:3851166; identified by sequence similarity; putative.
  
 
 0.836
hap
Hemagglutinin/protease; May play a role in the pathogenesis of cholera. Hap nicks and activates the A subunit of cholera enterotoxin and related enterotoxins.
 
  
 0.817
VC_0157
Alkaline serine protease; Similar to GB:M25499 SP:P16588 PID:155251; identified by sequence similarity; putative; Belongs to the peptidase S8 family.
 
 
 0.816
VC_A0065
Hypothetical protein; Identified by Glimmer2; putative.
  
  
 0.811
rtxA
RTX toxin RtxA; [Multifunctional-autoprocessing repeats-in-toxin]: Precursor of a multifunctional toxin that causes destruction of the actin cytoskeleton by covalent cross-linking of actin and inactivation of Rho GTPases when translocated into the host cytoplasm. Upon translocation into the host cell, undergoes autoprocessing in cis mediated by the peptidase C80 domain (also named CPD domain): the protease activity is activated upon binding inositol hexakisphosphate (InsP6) present at the host cell membrane and delivers the Cysteine protease domain-containing toxin F3 chain to the host [...]

VC_0414
Hypothetical protein; Identified by Glimmer2; putative.
 
  
 0.781
guaB
Inosine-5`-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
    
  0.759
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
    
  0.749
VC_A0027
Chitinase; Similar to SP:P32823 PID:216207; identified by sequence similarity; putative.
  
 
 0.733
VC_1606
Conserved hypothetical protein; Identified by Glimmer2; putative.
  
 
 
 0.720
