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 match to protein family HMM TIGR01172. (205 aa)    
Predicted Functional Partners:
cysK
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.
 
 0.996
cysS
cysteinyl-tRNA synthetase; Identified by match to protein family HMM PF01406; match to protein family HMM PF09190; match to protein family HMM PF09334; match to protein family HMM TIGR00435; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
  
 0.985
sdhA
L-serine dehydratase, iron-sulfur-dependent, alpha subunit; Identified by match to protein family HMM PF03313; match to protein family HMM TIGR00718; Belongs to the iron-sulfur dependent L-serine dehydratase family.
     
 0.906
sdhB
L-serine dehydratase, iron-sulfur-dependent, beta subunit; Identified by match to protein family HMM PF01842; match to protein family HMM PF03315; match to protein family HMM TIGR00719; Belongs to the iron-sulfur dependent L-serine dehydratase family.
     
 0.906
serB
Phosphoserine phosphatase SerB; Identified by match to protein family HMM PF00702; match to protein family HMM TIGR00338; match to protein family HMM TIGR01488.
    
 0.857
hom
Homoserine dehydrogenase; Identified by match to protein family HMM PF00742; match to protein family HMM PF01842; match to protein family HMM PF03447.

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.
     
 0.833
thrB
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
     
 0.828
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.
    
 0.812
trpA-1
Tryptophan synthase, alpha subunit; Identified by match to protein family HMM PF00290; match to protein family HMM TIGR00262.
