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

tcpPToxin co-regulated pilus biosynthesis protein P; Involved in TCP pilus biogenesis. (221 aa)    
Predicted Functional Partners:
tcpH
Toxin co-regulated pilus biosynthesis protein H; Involved in TCP pilus biogenesis.
     
 0.975
toxS
Regulatory protein ToxS; Interacts with ToxR and stimulates its activity.
    
 0.897
tcpN
TCP pilus virulence regulatory protein; Probable regulatory protein for the tcp operon.
      
 0.623
toxR
Cholera toxin transcriptional activator; This transcription activator controls cholera toxin, pilus colonization factor and outer membrane protein expression in V.cholerae. It binds to the 5'-TTTTGAT-3' tandemly repeated DNA sequence in the cholera toxin promoter region. ToxS interacts with the C-terminal periplasmic domain of ToxR, stimulating its activity. It activates transcription at the promoters for tcpI and tcpA and this is presumably via ToxT.
      
 0.600
tcpA
Toxin co-regulated pilin; Constituent of pili, which may be involved in adhesion of V.cholerae to the host intestinal epithelium.
      
 0.491
VC_2561
uroporphyrin-III C-methyltransferase; Similar to SP:P11098 GB:X14202 PID:581142 PID:606302 GB:U00096; identified by sequence similarity; putative; Belongs to the precorrin methyltransferase family.
    
 0.482
VC_1363
Siroheme synthase component enzyme; Similar to PID:576655; identified by sequence similarity; putative.
    
  0.467
hemE
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
     
 0.461
hemC
Porphobilinogen deaminase; Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family.
     
 0.454
VC_0119
uroporphyrinogen-III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
     
 0.451
