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

sahHAdenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine. (441 aa)    
Predicted Functional Partners:
metK
S-adenosylmethionine synthetase; Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.
 
 
 0.942
cysK
Cystathionine beta-synthase.
  
 0.759
metB
Cystathionine beta-lyase.
  
 0.685
Lcin_2365
Adenosylhomocysteinase.
  
  
 
0.677
tufA_2
Elongation factor Tu (EF-Tu); This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.
   
  
 0.577
carA
Carbamoyl-phosphate synthetase, glutamine (small subunit); Belongs to the CarA family.
       0.551
nuoI
NADH-quinone oxidoreductase chain I; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.
   
 
  0.546
pnp
Polynucleotide phosphorylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
  
    0.516
lysAC
Diaminopimelate decarboxylase, aspartate kinase (fusion of lysA and lysC); Belongs to the Orn/Lys/Arg decarboxylase class-II family.
   
 
 0.491
metX
Alpha/beta hydrolase.
     
 0.448
