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

ahcYAdenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine. (418 aa)    
Predicted Functional Partners:
metH
Methionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
  
 
 0.952
metK
Methionine adenosyltransferase; 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.
 
 
 0.926
NIDE0862
Putative Adenosylhomocysteine nucleosidase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
    
 0.923
NIDE1817
Homologs of previously reported genes of unknown function.
  
 
  0.902
NIDE1240
Conserved protein of unknown function, putative 4Fe-4S ferredoxin; Homologs of previously reported genes of unknown function; 2600971, 3932661.
     
  0.900
cysK
Cysteine synthase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 0.866
hom
Homoserine dehydrogenase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
   
 
  0.816
thrH
Homoserine kinase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
    
  0.801
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
  
 0.751
NIDE0844
Protein of unknown function; No homology to any previously reported sequences.
       0.682
