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

ahcYS-adenosyl-L-homocysteine hydrolase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine. (468 aa)    
Predicted Functional Partners:
metE
5-methyltetrahydropteroyltriglutamate-- homocysteine 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.
 
 
 0.984
metH
B12-dependent methionine 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.
  
 
 0.973
metZ
O-succinylhomoserine sulfhydrylase; Catalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide.
  
 0.935
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.

AHF04649.1
Pyridoxal-5'-phosphate-dependent protein subunit beta; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 0.925
AHF03841.1
O-acetylhomoserine aminocarboxypropyltransferase; Catalyzes the formation of L-methionine and acetate from O-acetyl-L-homoserine and methanethiol; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
 0.915
ilvA
L-threonine dehydratase biosynthetic IlvA; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA.

AHF03885.1
Homoserine dehydrogenase; Catalyzes the formation of L-aspartate 4-semialdehyde from L-homoserine; Derived by automated computational analysis using gene prediction method: Protein Homology.
   
 
  0.818
AHF04757.1
5,10-methylenetetrahydrofolate reductase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the methylenetetrahydrofolate reductase family.
  
  
 0.753
guaB
Inosine 5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
