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

nadCNicotinate-nucleotide pyrophosphorylase; silverDB:etchr00794; Belongs to the NadC/ModD family. (296 aa)    
Predicted Functional Partners:
nadB
L-aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
  
 0.997
nadA
Quinolinate synthetase A; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate; Belongs to the quinolinate synthase A family. Type 1 subfamily.
 
 
 0.997
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.
   
 0.946
nadR
Transcriptional regulator NadR; silverDB:etchr00666.
     
 0.942
nadD
Nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
    
 0.936
cinA-2
Probable competence-damaged protein; silverDB:etchr02657; Belongs to the CinA family.
     
 0.915
surE
5'/3'-nucleotidase SurE; Nucleotidase with a broad substrate specificity as it can dephosphorylate various ribo- and deoxyribonucleoside 5'-monophosphates and ribonucleoside 3'-monophosphates with highest affinity to 3'-AMP. Also hydrolyzes polyphosphate (exopolyphosphatase activity) with the preference for short-chain-length substrates (P20-25). Might be involved in the regulation of dNTP and NTP pools, and in the turnover of 3'-mononucleotides produced by numerous intracellular RNases (T1, T2, and F) during the degradation of various RNAs.
     
 0.903
mazG
Hypothetical protein MazG; silverDB:etchr02710.
    
  0.903
nudC
NADH pyrophosphatase; silverDB:etchr00172.
     
 0.901
yjjG
Nucleoside 5'-monophosphate phosphohydrolase; silverDB:etchr00602.
     
 0.900
