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

Score
metAAHomoserine O-succinyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine; Belongs to the MetA family. (308 aa)    
Predicted Functional Partners:
Pden_1933
KEGG: sit:TM1040_0585 O-acetylhomoserine/O-acetylserine sulfhydrylase; TIGRFAM: O-acetylhomoserine/O-acetylserine sulfhydrylase; PFAM: Cys/Met metabolism pyridoxal-phosphate-dependent enzymes.
 
 
 0.990
metZ
O-succinylhomoserine sulfhydrylase; Catalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide.
 
 
 0.981
Pden_3678
PFAM: homoserine dehydrogenase; amino acid-binding ACT domain protein; homoserine dehydrogenase, NAD-binding; KEGG: rsp:RSP_0403 homoserine dehydrogenase.
  
 
 0.943
Pden_2319
TIGRFAM: 5,10-methylenetetrahydrofolate reductase; PFAM: methylenetetrahydrofolate reductase; KEGG: rsp:RSP_2172 5,10-methylenetetrahydrofolate reductase; Belongs to the methylenetetrahydrofolate reductase family.
  
  
 0.917
Pden_4498
KEGG: rsp:RSP_0009 hypothetical protein.
 
     0.898
Pden_1935
Methionine synthase (B12-dependent); 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.
  
  
 0.877
Pden_4132
KEGG: rsp:RSP_0361 probable L-serine dehydratase protein; TIGRFAM: L-serine dehydratase 1; PFAM: serine dehydratase alpha chain; serine dehydratase beta chain; Belongs to the iron-sulfur dependent L-serine dehydratase family.
     
 0.821
trpB
Tryptophan synthase, beta chain; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
    
  0.820
Pden_0285
PFAM: Pyridoxal-5'-phosphate-dependent enzyme, beta subunit; KEGG: ret:RHE_PF00182 probable threonine dehydratase protein.
   
 
 0.818
ilvA
L-threonine ammonia-lyase; 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.
