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

sync_1969Identified by match to protein family HMM PF01725. (200 aa)    
Predicted Functional Partners:
rph
Ribonuclease PH; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.
 
    0.685
guaA
GMP synthase, glutamine-hydrolyzing; Catalyzes the synthesis of GMP from XMP.
 
  
 0.621
nusG
Transcription termination/antitermination factor NusG; Participates in transcription elongation, termination and antitermination.
  
    0.491
sync_0156
Polyketide synthase, putative; Identified by match to protein family HMM PF00106; match to protein family HMM PF00107; match to protein family HMM PF00109; match to protein family HMM PF00550; match to protein family HMM PF01073; match to protein family HMM PF01370; match to protein family HMM PF02801; match to protein family HMM PF07993; match to protein family HMM TIGR01746.
   
 
 0.466
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
  
 0.457
ribD
Riboflavin biosynthesis protein RibD; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
     
 0.443
purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
 
 
 
 0.441
folP
Dihydropteroate synthase; Catalyzes the condensation of para-aminobenzoate (pABA) with 6-hydroxymethyl-7,8-dihydropterin diphosphate (DHPt-PP) to form 7,8- dihydropteroate (H2Pte), the immediate precursor of folate derivatives.
  
  
 0.415
folE
GTP cyclohydrolase I; Identified by match to protein family HMM PF01227; match to protein family HMM TIGR00063.
