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
metZO-succinylhomoserine sulfhydrylase; Catalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide. (389 aa)    
Predicted Functional Partners:
cysK
Cysteine synthase A; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the cysteine synthase/cystathionine beta- synthase family.
 
 0.971
metE
5-methyltetrahydropteroyltriglutamate-- homocysteine methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.
  
 
 0.963
metXS
Homoserine O-acetyltransferase; Transfers a succinyl group from succinyl-CoA to L-homoserine, forming succinyl-L-homoserine.
  
 0.956
luxS
S-ribosylhomocysteine lyase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD). Belongs to the LuxS family.
  
 
 0.937
cysI
Sulfite reductase subunit beta; Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
  
 0.921
ARB04513.1
Cystathionine gamma-synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 
0.917
Hom
Homoserine dehydrogenase; Catalyzes the formation of L-aspartate 4-semialdehyde from L-homoserine; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.853
ilvA
PLP-dependent 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.
  
 
 0.826
thrB
Homoserine kinase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the pseudomonas-type ThrB family.
     
  0.800
metF
5,10-methylenetetrahydrofolate reductase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the methylenetetrahydrofolate reductase family.
  
 
 0.673
