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

metEMethionine synthase; Catalyzes the transfer of a methyl group to L-homocysteine resulting in methionine formation. Can use methylcobalamin and methylcobinamide as methyl donors, but methylcobalamin is not considered to be the physiological substrate. It was proposed that, in vivo, a so-far-unidentified enzyme catalyzes methyltransfer from 5- methyltetrahydromethanopterin (5-CH3-H4MPT) to a corrinoid protein, and that the MetE gene product catalyzes the further transfer to L- homocysteine. Is not active with L-cysteine, coenzyme M, coenzyme B, glutathione or dithiothreitol as substrate. (309 aa)    
Predicted Functional Partners:
ahcY
S-adenosylhomocysteine hydrolase; Catalyzes the hydrolysis of S-inosyl-L-homocysteine (SIH) to L-homocysteine (Hcy) and inosine. Likely functions in a S-adenosyl-L- methionine (SAM) recycling pathway from S-adenosyl-L-homocysteine (SAH) produced from SAM-dependent methylation reactions. Can also catalyze the reverse reaction in vitro, i.e. the synthesis of SIH from Hcy and inosine; Belongs to the adenosylhomocysteinase family.

ADL57618.1
Peroxiredoxin-related protein.
 
     0.968
metK
S-adenosylmethionine synthetase; Catalyzes the formation of S-adenosylmethionine from methionine and ATP; Belongs to the AdoMet synthase 2 family.
  
  
 0.934
ADL58765.1
Conserved hypothetical protein.
 
     0.929
thyA
Thymidylate synthase; May catalyze the biosynthesis of dTMP using an unknown cosubstrate. In vitro, also catalyzes the dehalogenation of 5-bromo- deoxyuridine monophosphate (Br-dUMP) and the tritium exchange of [5- 3H]deoxyuridine monophosphate ([5-3H]dUMP).
     
 0.926
metS
methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
    
 0.917
ADL58766.1
Conserved hypothetical protein.
       0.916
ADL58840.1
CBS domain containing protein.
     
 0.901
ADL58839.1
Conserved hypothetical protein containing a ferredoxin domain.
     
  0.900
