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

cysD-2Putative O-Acetyl homoserine sulfhydrylase. (438 aa)    
Predicted Functional Partners:
metA
Putative homoserine O-succinyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine; Belongs to the MetA family.
 
 
 0.993
SYNW0674
Possible cystathionine gamma-synthase.
 
 
 0.977
metH
Putative 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.
  
 
 0.962
ahcY,
Putative adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
     
 0.917
thrA,hom
Homoserine dehydrogenase; Putative assignment.
 
 
 0.885
metB
Putative cystathionine gamma-synthase.
 
 
0.873
cysK1
O-acetylserine (thiol)-lyase A; Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
 
 0.837
cysK2
O-acetylserine (thiol)-lyase A; Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
 
 0.837
thrB
Putative homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
    
  0.812
ilvA
Threonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA.
