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

metHMethionine 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. (1206 aa)    
Predicted Functional Partners:
sync_2618
Identified by match to protein family HMM PF02219; Belongs to the methylenetetrahydrofolate reductase family.
 
 
 0.999
sync_0622
Possible cystathionine gamma-synthase; Identified by match to protein family HMM PF01053.
  
 
 0.973
metB
Cystathionine beta-lyase/cystathionine gamma-synthase; Identified by match to protein family HMM PF01053.
  
 
 0.973
gcvT
Glycine cleavage system T protein; The glycine cleavage system catalyzes the degradation of glycine.
  
 
 0.962
ahcY
Adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
  
 
 0.961
metK
S-adenosylmethionine 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.
  
 
 0.961
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.
     
 0.952
hom
Homoserine dehydrogenase; Identified by match to protein family HMM PF00742; match to protein family HMM PF01842; match to protein family HMM PF03447.
  
 
 0.944
fmt
methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
    
 0.932
thiol
O-acetylhomoserine sulfhydrylase; Identified by match to protein family HMM PF01041; match to protein family HMM PF01053; match to protein family HMM TIGR01326.
