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

Score
cysK-2Cysteine synthase A; Belongs to the cysteine synthase/cystathionine beta- synthase family. (322 aa)    
Predicted Functional Partners:
metB
Cystathionine gamma-synthase.
  
 0.961
metC
Putative cystathionine gamma-synthase.
  
 0.961
sir
Sulfite reductase, ferredoxin dependent; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
  
 
 0.930
aspC
Aminotransferases class-I.
    
 0.904
cysK
Cysteine synthase A; Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
  
 
0.904
metH
5-methyltetrahydrofolate--homocysteine methyltransferase; 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.
  
 
 0.897
ahcY
Adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
  
 0.846
cysD-2
O-acetylhomoserine/O-acetylserine sulfhydrylase.
  
 
 0.834
pepN
Peptidase M, neutral zinc metallopeptidase, zinc-binding site.
 
   
 0.827
pepA
Leucyl aminopeptidase; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides.
    
 0.819
