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). (293 aa)    
Predicted Functional Partners:
folD
Methenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
 
 0.949
glyA
Glycine hydroxymethyltransferase; 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.
  
 
 0.937
purN
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.
 
  
0.929
purT
Phosphoribosylglycinamide formyltransferase 2; Involved in the de novo purine biosynthesis. Catalyzes the transfer of formate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR). Formate is provided by PurU via hydrolysis of 10-formyl-tetrahydrofolate; Belongs to the PurK/PurT family.
 
  
 0.928
Asuc_0714
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
    
 0.913
Asuc_1264
TIGRFAM: formate dehydrogenase, alpha subunit; PFAM: molybdopterin oxidoreductase; molydopterin dinucleotide-binding region; KEGG: msu:MS0891 anaerobic dehydrogenases, typically selenocysteine-containing; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
    
  0.901
Asuc_1265
Formate dehydrogenase; PFAM: molybdopterin oxidoreductase Fe4S4 region; KEGG: msu:MS0892 anaerobic dehydrogenases, typically selenocysteine-containing.
    
  0.901
Asuc_1262
TIGRFAM: formate dehydrogenase, gamma subunit; KEGG: msu:MS1028 cytochrome b subunit of formate dehydrogenase.
     
  0.900
Asuc_1263
Formate dehydrogenase, beta subunit; The beta chain is an electron transfer unit containing 4 cysteine clusters involved in the formation of iron-sulfur centers.
     
  0.900
Asuc_1704
TIGRFAM: formate dehydrogenase, alpha subunit; PFAM: ferredoxin; 4Fe-4S ferredoxin iron-sulfur binding domain protein; molybdopterin oxidoreductase; molydopterin dinucleotide-binding region; molybdopterin oxidoreductase Fe4S4 region; KEGG: msu:MS0732 uncharacterized anaerobic dehydrogenase.
