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.

nadDNicotinate (nicotinamide) nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD). (210 aa)    
Predicted Functional Partners:
SGO_0448
Conserved hypothetical protein TIGR00488; Identified by match to protein family HMM PF01966; match to protein family HMM TIGR00488.
 
    0.998
nadE
NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
  
 
 0.988
SGO_0582
Nicotinate phosphoribosyltransferase, putative; 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.
 
 
 0.979
nadR
Transcription regulator; Identified by match to protein family HMM TIGR00125.
     
 0.960
rsfS
Iojap-related 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.
  
  
 0.954
SGO_0446
Conserved hypothetical protein TIGR00253; Identified by match to protein family HMM PF01985; match to protein family HMM TIGR00253.
  
  
 0.945
ppnK
Probable 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
NAD-dependent deacetylase (Regulatory protein SIR2-like protein); NAD-dependent protein deacetylase which modulates the activities of several enzymes which are inactive in their acetylated form; Belongs to the sirtuin family. Class U subfamily.
   
 0.923
SGO_0449
Identified by match to protein family HMM PF00857.
     
 0.869
SGO_1823
Conserved hypothetical protein TIGR00046; Specifically methylates the N3 position of the uracil ring of uridine 1498 (m3U1498) in 16S rRNA. Acts on the fully assembled 30S ribosomal subunit.
