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

pncANicotinamidase/pyrazinamidase; Catalyzes the deamidation of nicotinamide (NAM) into nicotinate. Likely functions in the cyclical salvage pathway for production of NAD from nicotinamide. (213 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.
 
 
 0.997
cobB
Deacetylase of acs and cheY, chemotaxis regulator; NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form. Activates the enzyme acetyl-CoA synthetase by deacetylating 'Lys-609' in the inactive, acetylated form of the enzyme. May also modulate the activity of other propionyl-adenosine monophosphate (AMP)-forming enzymes. Belongs to the sirtuin family. Class III subfamily.
  
 0.933
ansA
Cytoplasmic L-asparaginase 1; Protein involved in cellular amino acid catabolic process; Belongs to the asparaginase 1 family.
  
  
 0.918
nadE
NAD synthetase, NH3/glutamine-dependent; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
  
  
 0.904
katG
Catalase-peroxidase HPI, heme b-containing; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity. Displays also NADH oxidase, INH lyase and isonicotinoyl-NAD synthase activity; Belongs to the peroxidase family. Peroxidase/catalase subfamily.
      
 0.904
nadD
Nicotinic acid mononucleotide adenylyltransferase, NAD(P)-dependent; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD). Belongs to the NadD family.
  
  
 0.901
deoD
Purine nucleoside phosphorylase 1; Cleavage of guanosine or inosine to respective bases and sugar-1-phosphate molecules.
    
 0.901
nadC
Quinolinate phosphoribosyltransferase; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
   
 
 0.842
ycaC
Putative isochorismatase family hydrolase; Protein involved in cellular amino acid catabolic process.
      
 0.840
rpoB
RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
      
 0.829
