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

metEB12-independent 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase MetE; 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. (758 aa)    
Predicted Functional Partners:
metH
B12-dependent 5-methyltetrahydrofolate--homocysteine methyltransferase MetH; 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.
  
 
 0.985
metK
S-adenosylmethionine synthetase MetK; 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.
  
 0.976
ahcY
S-adenosyl-L-homocysteine hydrolase AhcY; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
  
 
 0.969
metG
methionyl-tRNA synthetase MetG; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation; Belongs to the class-I aminoacyl-tRNA synthetase family.
     
 0.903
AHB88441.1
Ferredoxin.
     
  0.900
AHB89027.1
Protein of unknown function DUF39.
     
  0.900
metF
5, 10-methylenetetrahydrofolate reductase MetF; Belongs to the methylenetetrahydrofolate reductase family.
  
 
 0.895
thrA
Homoserine dehydrogenase ThrA.
   
 
 0.880
cysK
Cysteine synthase CysK; Belongs to the cysteine synthase/cystathionine beta- synthase family.
   
 
 0.847
thrB
Homoserine kinase ThrB; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
