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

nadK-2Putative sugar 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. (281 aa)    
Predicted Functional Partners:
AFZ71706.1
Putative sugar kinase; PFAM: ATP-NAD kinase.
  
  
 0.958
nadE
NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
 
  
 0.935
AFZ73267.1
NAD-dependent protein deacetylase, SIR2 family; PFAM: Sir2 family.
  
 
 0.921
AFZ72011.1
PFAM: Cytidylyltransferase; TIGRFAM: nicotinamide-nucleotide adenylyltransferase; cytidyltransferase-related domain.
    
 0.913
srp54
Signal recognition particle GTPase; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Belongs to the GTP-binding SRP family. SRP54 subfamily.
 
    0.552
AFZ73172.1
Geranylgeranyl pyrophosphate synthase; PFAM: Polyprenyl synthetase; Belongs to the FPP/GGPP synthase family.
 
 
   0.507
AFZ73725.1
Geranylgeranyl pyrophosphate synthase; PFAM: Polyprenyl synthetase; Belongs to the FPP/GGPP synthase family.
 
 
   0.491
uppS
Undecaprenyl diphosphate synthase; Catalyzes the sequential condensation of isopentenyl diphosphate (IPP) with geranylgeranyl diphosphate (GGPP) to yield (2Z,6Z,10Z,14Z,18Z,22Z,26Z,30E,34E,38E)-undecaprenyl diphosphate (tritrans,heptacis-UPP). It is probably the precursor of glycosyl carrier lipids.
 
   
 0.443
AFZ71704.1
Geranylgeranyl pyrophosphate synthase; PFAM: Polyprenyl synthetase; Belongs to the FPP/GGPP synthase family.
 
 
   0.434
truA
Pseudouridylate synthase; Formation of pseudouridine at positions 38, 39 and 40 in the anticodon stem and loop of transfer RNAs; Belongs to the tRNA pseudouridine synthase TruA family.
 
    0.428
