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.

pnuCNMN family, nucleoside/purine/pyrimidine transporter; Required for nicotinamide riboside transport across the inner membrane. (239 aa)    
Predicted Functional Partners:
nadA
Quinolinate synthetase, A protein; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate.
 
  
 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 [...]
  
 0.987
nadB
Quinolinate synthetase, B protein; Catalyzes the oxidation of L-aspartate to iminoaspartate.
   
  
 0.949
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.
     
 0.914
nadD
Putative nicotinic acid mononucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
     
 0.908
nadE
NAD synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
      
 0.867
pncA
Nicotinamidase/ pyrazinamidase; Similar to E. coli orf, hypothetical protein (AAC74838.1); Blastp hit to AAC74838.1 (219 aa), 80% identity in aa 7 - 219.
  
  
 0.865
nadC
Quinolinate phosphoribosyltransferase; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
      
 0.860
STM3631
Similar to E. coli putative permease (AAC75926.1); Blastp hit to AAC75926.1 (505 aa), 27% identity in aa 54 - 466.
      
 0.618
yacL
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC73230.1); Blastp hit to AAC73230.1 (136 aa), 85% identity in aa 17 - 135; Belongs to the UPF0231 family.
