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

purUFormyltetrahydrofolate deformylase; Catalyzes the hydrolysis of 10-formyltetrahydrofolate (formyl-FH4) to formate and tetrahydrofolate (FH4). (294 aa)    
Predicted Functional Partners:
folD
5,10-methylenetetrahydrofolate dehydrogenase (NADP+); Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
 
 0.992
folA
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
    
 0.963
SHMT
Serine hydroxymethyltransferase protein; 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.
  
 
 0.943
purN
Formyltetrahydrofolate-dependent phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
 
 
0.932
RSP_2124
Methionine synthase I; IMG reference gene:2512954048; PFAM: Homocysteine S-methyltransferase.
  
 
 0.927
gcvT
Putative aminomethyltransferase, tetrahydrofolate dependent; IMG reference gene:2512954121; PFAM: Aminomethyltransferase folate-binding domain; Glycine cleavage T-protein C-terminal barrel domain; TIGRFAM: glycine cleavage system T protein.
  
 
 0.926
RSP_3347
Methionine synthase (B12-dependent); IMG reference gene:2512956856; PFAM: Homocysteine S-methyltransferase.
    
 0.920
RSP_2768
Pterin binding enzyme; IMG reference gene:2512954718; PFAM: Pterin binding enzyme.
  
 
  0.902
RSP_3346
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.
    
  0.902
fdsG
Formate dehydrogenase gamma subunit; IMG reference gene:2512956120; PFAM: Respiratory-chain NADH dehydrogenase 24 Kd subunit.
     
  0.900
