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

nadDPutative nicotinic acid mononucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD). (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.
  
 
 0.996
nadE
NAD synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
 
 
 0.996
nadC
Quinolinate phosphoribosyltransferase; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
    
 0.993
nadR
Trifunctional protein; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity catalyzes the transfer of the A [...]
     
 0.992
yfjB
Putative 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. It can use ATP and other nucleoside triphosphates as a source of phosphorus. NADH cannot replace NAD as a substrate.
 
 
 0.982
ygaD
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC75742.1); Blastp hit to AAC75742.1 (165 aa), 92% identity in aa 1 - 165; Belongs to the CinA family.
 
 
 0.957
ybeB
Putative ACR, homolog of plant Iojap protein; 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.
  
 0.956
cobB
Putative nicotinate-nucleotide dimethylbenzimidazolephosphoribosltransferase; 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 (By similarity). 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. Overexpression compensates for a cobT deletion, suggesting it may have [...]
   
 0.936
nadB
Quinolinate synthetase, B protein; Catalyzes the oxidation of L-aspartate to iminoaspartate.
     
 0.932
nadA
Quinolinate synthetase, A protein; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate.
