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). (226 aa)    
Predicted Functional Partners:
nadE
NAD(+) synthase (glutamine-hydrolyzing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
 
 
 0.958
cinA
CinA-like protein; Function of strongly homologous gene; cell process; Belongs to the CinA family.
  
 
 0.956
rsfS
Conserved protein of unknown function, Iojap family; 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.
 
  
 0.955
ppnK
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.
  
 
 0.929
pncB
Nicotinate phosphoribosyltransferase; 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.
 
 
 0.929
nadC
Nicotinate-nucleotide diphosphorylase (carboxylating); Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the NadC/ModD family.
    
 0.926
npdA
NAD-dependent deacetylase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the sirtuin family. Class III subfamily.
   
 0.919
NIDE4241
HAD-like hydrolase, putative purine nucleotidase; Function of strongly homologous gene; enzyme.
    
 0.914
surE
5'-nucleotidase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
     
 0.902
sthA
Soluble pyridine nucleotide transhydrogenase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
   
 
 0.900
