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

capACapsular polyglutamate synthetase; Seems to be required for maximum PGA (gamma-polyglutamic acid) production; Belongs to the CapA family. (380 aa)    
Predicted Functional Partners:
capC
Capsular polyglutamate amide ligase/translocase subunit; Required for PGA (gamma-polyglutamic acid) biosynthesis.
 
  
 0.998
capB
Capsular polyglutamate synthetase (ATP-dependent amide ligase); Catalyzes the biosynthesis of PGA (gamma-polyglutamic acid) from L-glutamate. Both the 44-kDa and the 33-kDa forms are required for PGA synthesis.
 
  
 0.995
capE
Factor required for polyglutamate synthesis; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type f: factor.
  
  
 0.973
yxiO
Putative efflux transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.
      
 0.887
pgdS
gamma-DD-glutamyl hydrolase (PGA depolymerase); Cleaves, in an endo-type manner, the gamma-glutamyl bond between D-glutamate and L-glutamate of poly-gamma-glutamate (PGA).
 
   
 0.882
yodJ
D-alanyl-D-alanine carboxypeptidase lipoprotein; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
     0.862
dacB
D-alanyl-D-alanine carboxypeptidase (penicillin-binding protein 5*); Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors. Required specifically for the synthesis of the spore form of peptidoglycan (cortex).
 
      0.833
pncB
Nicotinate phosphoribosyltransferase; Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP; Belongs to the NAPRTase family.
  
    0.724
ptkA
Protein tyrosine kinase; May be involved in the regulation of capsular polysaccharide biosynthesis. Autophosphorylates in vitro. Phosphorylates and activates in vitro two UDP-glucose dehydrogenases, YwqF and TuaD, as well as the DNA-binding proteins Ssb and SsbB; Belongs to the CpsD/CapB family.
  
  
 0.438
epsB
Protein tyrosine kinase; Evidence 2b: Function of strongly homologous gene; enzyme; Belongs to the CpsD/CapB family.
  
  
 0.437
