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

cbpDCholine binding protein D. (448 aa)    
Predicted Functional Partners:
lytC
1,4-beta-N-acetylmuramidase.
 
  
 0.970
cbpG
Choline binding protein G.
      
 0.862
comE
Response regulator; Required for induction of competence.
      
 0.851
comD
Histidine protein kinase; Required for induction of competence.
      
 0.810
ply
Pneumolysin (sulfhydryl-activated toxin that lyses cholesterol containing membranes); Sulfhydryl-activated toxin that causes cytolysis by forming pores in cholesterol containing host membranes. After binding to target membranes, the protein undergoes a major conformation change, leading to its insertion in the host membrane and formation of an oligomeric pore complex. Cholesterol may be required for binding to host membranes, membrane insertion and pore formation. Can be reversibly inactivated by oxidation (By similarity).
   
  
 0.807
flpA
Fibronectin-binding protein-like protein A; Part of the ribosome quality control system (RQC). Recruits Ala-charged tRNA and directs the elongation of stalled nascent chains on 50S ribosomal subunits, leading to non-templated C-terminal Ala extensions (Ala tail). The Ala tail promotes nascent chain degradation. May add between 1 and at least 8 Ala residues. Binds to stalled 50S ribosomal subunits.

zmpB
Zinc metalloprotease; Similar to IgA1 protease.
     
 0.741
comC
Competence stimulating peptide precursor (CSP); Acts as a pheromone, induces cells to develop competence for genetic transformation; Belongs to the ComC family.
      
 0.723
spr0583
Hypothetical protein; Similar to 1,4-beta-N-acetylmuramidase.
  
   
 0.716
luxS
Autoinducer-2 production protein; 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) (By similarity); Belongs to the LuxS family.
