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

Score
prtRIIArginine-specific cysteine proteinase; Thiol protease. Acts synergistically with RgpA to catalyze the maturation of fimbrial subunits, such as FimA (By similarity). Its proteolytic activity is a major factor in both periodontal tissue destruction and in evasion of host defense mechanisms (Probable). (736 aa)    
Predicted Functional Partners:
hagE
Hemagglutinin protein HagE; Cleaves human complement component C3. May enable P.gingivalis to evade complement-mediated killing during the immune response. Plays an important role in soft tissue infections and is a virulence factor; Belongs to the peptidase C25 family.
  
  
0.901
PG_1424
Peptidylarginine deiminase; Deiminates the guanidino group of C-terminal arginine residues on a variety of peptides, including the vasoregulatory peptide-hormone bradykinin, to yield ammonia and a citrulline residue. May promote the growth of the pathogen in the periodontal pocket by producing ammonia, ammonia having a protective effect during acidic cleaning cycles in the mouth.
 
   
 0.888
PG_0410
Hypothetical protein; Identified by Glimmer2; putative.
  
    0.776
PG_0232
Zinc carboxypeptidase, putative.
 
   
 0.759
PG_0505
Hypothetical protein; Identified by Glimmer2; putative.
       0.723
porT
porT protein.
  
   
 0.614
fimA
Fimbrilin; Structural subunit of the major fimbriae. These long, filamentous pili are attached to the cell surface; they mediate biofilm formation, adhesion onto host cells and onto other bacteria that are part of the oral microbiome. They play an important role in the invasion of periodontal tissues. Fimbriae and their constituents are major virulence factors. FimA proteins from different strains have highly divergent sequences, and this has been used for classification. The sequence-based classification correlates with pathogenicity; Belongs to the bacteroidetes fimbrillin superfamil [...]
      
 0.560
porR
Pigmentation and extracellular proteinase regulator; Belongs to the DegT/DnrJ/EryC1 family.
   
  
 0.552
prtC
Collagenase; Expresses collagenase activity. Hydrolyzes type I collagen. May play a role in virulence (By similarity).
      
 0.547
hmuY
hmuY protein.
      
 0.541
