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

SRA_02371
Aminotransferase; COG1168 Bifunctional PLP-dependent enzyme with beta-cystathionase and maltose regulon repressor activities.
    
 0.926
serC
Phosphoserine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine.
  
 
 0.924
cysS
COG0215 Cysteinyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 
 0.914
SRA_04436
Bifunctional homocysteine S-methyltransferase/5,10-methylenetetrahydrofolate reductase protein; COG0646 Methionine synthase I (cobalamin-dependent), methyltransferase domain.
  
 
 0.902
luxS
S-ribosylhomocysteinase; 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.
  
 
 0.875
gshAB
Bifunctional glutamate--cysteine ligase/glutathione synthetase; Synthesizes glutathione from L-glutamate and L-cysteine via gamma-L-glutamyl-L-cysteine; In the N-terminal section; belongs to the glutamate--cysteine ligase type 1 family. Type 2 subfamily.
    
 0.870
SRA_05651
COG2873 O-acetylhomoserine sulfhydrylase.
  
 
 0.858
metE
5-methyltetrahydropteroyltriglutamate-- homocysteine S-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.
   
 
 0.829
