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
cysMCysteine synthase. (322 aa)    
Predicted Functional Partners:
sir
Ferredoxin-sulfite reductase; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
  
 
 0.969
cysS
cysteinyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 
 0.913
aspC-2
Aspartate aminotransferase.
    
 0.901
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.
  
 
 0.878
ahcY
Adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
  
 0.841
pepA
Leucine aminopeptidase; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides.
    
 0.823
cysE-2
Serine acetyltransferase.
  
 0.822
cysE
Serine acetyltransferase.
  
 0.819
MAE_41580
Serine acetyltransferase.
  
 0.819
cysE-3
Serine acetyltransferase.
  
 0.819
