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

sir2Transcriptional regulator Sir2 family; NAD-dependent protein deacetylase which modulates the activities of several enzymes which are inactive in their acetylated form. Deacetylates the N-terminal lysine residue of Alba, the major archaeal chromatin protein and that, in turn, increases Alba's DNA binding affinity, thereby repressing transcription; Belongs to the sirtuin family. Class U subfamily. (260 aa)    
Predicted Functional Partners:
nadM
Nicotinamide-nucleotide adenylyltransferase.
   
 
  0.971
nadE1
NH(3)-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
    
 0.949
rrnAC0727
ATP-NAD kinase.
  
 
 0.928
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.
  
 
 0.928
iunH2
Inosine-uridine preferring nucleoside hydrolase.
  
 
 0.915
rrnAC0821
ATP-NAD kinase.
     
  0.900
aup
Acetoin utilization protein.
   
 
 0.837
map
Methionine aminopeptidase; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val); Belongs to the peptidase M24A family. Methionine aminopeptidase archaeal type 2 subfamily.
   
 
 0.825
dnaK
Chaperone protein DnaK; Acts as a chaperone.
   
 0.749
gdhA1
NADP-specific glutamate dehydrogenase; Belongs to the Glu/Leu/Phe/Val dehydrogenases family.
  
 0.711
