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

nadDNicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD). (229 aa)    
Predicted Functional Partners:
nadE
Glutamine-dependent NAD(+)synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
 
 0.985
nadC
Nicotinate-nucleotide pyrophosphorylase; Belongs to the NadC/ModD family.
    
 0.979
rsfS
Ribosomal silencing factor RsfS; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.
 
  
 0.974
pncB1
Nicotinate phosphoribosyltransferase pncB1; Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Belongs to the NAPRTase family.
 
 
 0.969
T45_00557
Hypothetical protein.
     
 0.954
cinA_2
Putative competence-damage inducible protein; Belongs to the CinA family.
 
 
 0.949
ppnK
Inorganic polyphosphate/ATP-NAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.
 
 
 0.938
cobB_2
NAD-dependent protein deacetylase.
   
 0.936
nadB_2
L-aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
    
 0.936
nudC
NADH pyrophosphatase.
     
 0.899
