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.

ahcYAdenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine. (431 aa)    
Predicted Functional Partners:
metH-2
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.
  
 
 0.946
metK
S-adenosylmethionine synthase; 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.
  
 
 0.881
nuoI
NADH-quinone oxidoreductase subunit 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.
  
 
  0.786
cysK
Cysteine synthase; Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
 0.786
metC
Cystathionine beta-lyase MetC.
   
 0.774
mec
cysO-cysteine peptidase.
  
  0.744
hom
Homoserine dehydrogenase.
   
 
  0.735
tdcB
L-threonine dehydratase catabolic TdcB.
  
 
 0.729
pnp
Polyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
  
    0.727
thrB
Homoserine kinase; Belongs to the pseudomonas-type ThrB family.
    
  0.717
