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

metHB12-dependent homocysteine-N5-methyltetrahydrofolate transmethylase, repressor of metE and metF; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate. (1227 aa)    
Predicted Functional Partners:
metF
5,10-methylenetetrahydrofolate reductase; Residues 1 to 296 of 296 are 99.66 pct identical to residues 1 to 296 of 296 from Escherichia coli K-12 Strain MG1655: B3941; Belongs to the methylenetetrahydrofolate reductase family.
 
 
 0.997
metE
Tetrahydropteroyltriglutamate 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.
  
 
 0.991
thrA
Aspartokinase I, homoserine dehydrogenase I; Residues 1 to 820 of 820 are 99.75 pct identical to residues 1 to 820 of 820 from Escherichia coli K-12 Strain MG1655: B0002; In the C-terminal section; belongs to the homoserine dehydrogenase family.
  
 
 0.986
metL
Aspartokinase II and homoserine dehydrogenase II; Residues 1 to 810 of 810 are 99.87 pct identical to residues 1 to 810 of 810 from Escherichia coli K-12 Strain MG1655: B3940; In the C-terminal section; belongs to the homoserine dehydrogenase family.
  
 
 0.986
metB
Cystathionine gamma-synthase; Residues 1 to 386 of 386 are 99.48 pct identical to residues 1 to 386 of 386 from Escherichia coli K-12 Strain MG1655: B3939.
 
 
 0.979
metC
Cystathionine beta-lyase (beta-cystathionase); Residues 1 to 395 of 395 are 98.48 pct identical to residues 1 to 395 of 395 from Escherichia coli K-12 Strain MG1655: B3008.
  
 
 0.976
metK
Methionine adenosyltransferase 1 (AdoMet synthetase); Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.
  
 
 0.968
ygaG
Orf, hypothetical protein; 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.
    
 0.967
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.
     
 0.961
gcvT
Aminomethyltransferase (T protein; The glycine cleavage system catalyzes the degradation of glycine.
