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

metH_2Methionine synthase; 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. (1213 aa)    
Predicted Functional Partners:
yitJ
Bifunctional homocysteine S-methyltransferase/5,10-methylenetetrahydrofolate reductase.
 
 
0.999
metH_1
Methionine synthase.
 
 
0.993
mccB
Cystathionine gamma-lyase.
  
 
 0.988
metE_1
5-methyltetrahydropteroyltriglutamate-- homocysteine methyltransferase.
  
 
 0.988
metC_2
Cystathionine beta-lyase.
  
 
 0.988
metE_2
5-methyltetrahydropteroyltriglutamate-- homocysteine methyltransferase.
  
 
 0.988
mdeA
Methionine gamma-lyase.
  
 
 0.986
fhs
Formate--tetrahydrofolate ligase; Belongs to the formate--tetrahydrofolate ligase family.
  
 
 0.985
metK
S-adenosylmethionine synthase; 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.
  
 
 0.985
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.
