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
pncANicotinamidase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the isochorismatase family. (183 aa)    
Predicted Functional Partners:
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.
 
  
 0.989
rpoB
RNA polymerase (beta subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
      
 0.981
panD
Aspartate 1-decarboxylase; Catalyzes the pyruvoyl-dependent decarboxylation of aspartate to produce beta-alanine.
   
  
 0.975
gyrA
DNA gyrase (subunit A); A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
      
 0.947
rpsL
Ribosomal protein S12 (BS12); With S4 and S5 plays an important role in translational accuracy.
  
  
 0.941
rpfA
RNA degradation presenting factor (ribosomal protein S1 homolog); Plays a role in sporulation; Belongs to the bacterial ribosomal protein bS1 family.
   
  
 0.927
rsmG
7-methylguanosine methyltransferase (16S rRNA, nucleotide G527); Specifically methylates the N7 position of guanine in position 535 of 16S rRNA.
     
 0.923
nadD
Nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD); Belongs to the NadD family.
     
 0.885
nadC
Nicotinate-nucleotide pyrophosphorylase; Involved in the catabolism of quinolinic acid (QA).
  
 
 0.877
gyrB
DNA gyrase (subunit B); A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
