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

cysESerine O-acetyltransferase; Identified by similarity to SP:Q06750; match to protein family HMM PF00132; match to protein family HMM TIGR01172. (248 aa)    
Predicted Functional Partners:
cysK-2
Cysteine synthase A; Identified by match to protein family HMM PF00291; match to protein family HMM TIGR01136; match to protein family HMM TIGR01139; Belongs to the cysteine synthase/cystathionine beta- synthase family.
 
 0.990
cysK-1
Cysteine synthase A; Identified by match to protein family HMM PF00291; match to protein family HMM TIGR01136; match to protein family HMM TIGR01139; Belongs to the cysteine synthase/cystathionine beta- synthase family.
 
 0.988
cysS
cysteinyl-tRNA synthetase; Identified by match to protein family HMM PF01406; match to protein family HMM TIGR00435; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
  
 0.926
thiol
O-acetylhomoserine sulfhydrylase; Identified by match to protein family HMM PF01041; match to protein family HMM PF01053; match to protein family HMM TIGR01326.
    
 0.926
metB
Cystathionine beta-lyase/cystathionine gamma-synthase; Identified by match to protein family HMM PF01053.
  
 
 0.867
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
     
 0.843
thrB
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
     
 0.836
hom
Homoserine dehydrogenase; Identified by match to protein family HMM PF00742; match to protein family HMM PF01842; match to protein family HMM PF03447.
     
 0.821
trpA
Tryptophan synthase, alpha subunit; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.
     
 0.813
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.
