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

plu3517Unnamed protein product; Highly similar to homocysteine synthase. (424 aa)    
Predicted Functional Partners:
metA
Homoserine O-succinyltransferase (homoserine O-transsuccinylase) (HTS); Transfers a succinyl group from succinyl-CoA to L-homoserine, forming succinyl-L-homoserine; Belongs to the MetA family.
 
 
 0.981
plu0524
Unnamed protein product; Similar to cystathionine beta-synthase.
  
 
 0.942
metC
Cystathionine beta-lyase (CHL) (beta-cystathionase) (cysteine lyase).
 
 
0.935
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.
  
 
 0.935
plu3731
Aminotran_1_2 domain-containing protein; Unnamed protein product; Similar to aminotransferases.
   
 0.928
metB
Cystathionine gamma-synthase (CGS) (O-succinylhomoserine (Thiol)-lyase).
 
 
0.927
thrA
Aspartokinase I-homoserine dehydrogenase I; In the C-terminal section; belongs to the homoserine dehydrogenase family.
  
 
 0.906
luxS
Autoinducer-2 (AI-2) production protein LuxS; 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.
     
 0.906
metL
Bifunctional aspartokinase/homoserine dehydrogenase II (AKII-HDII) [Includes: Aspartokinase II; homoserine dehydrogenase II]; In the C-terminal section; belongs to the homoserine dehydrogenase family.
  
 
 0.906
plu1781
CoA_binding domain-containing protein; Unnamed protein product; Highly similar to unknown protein YccU of Escherichia coli.
      0.899
