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

fhsFormate--tetrahydrofolate ligase; Belongs to the formate--tetrahydrofolate ligase family. (556 aa)    
Predicted Functional Partners:
folD
Tetrahydrofolate dehydrogenase/cyclohydrolase bifunctional protein; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
 
 0.996
purH
Bifunctional purine biosynthesis protein.
  
 0.985
glyA
Serine 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.
  
 0.972
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.
  
 0.971
HM1_1889
Methenyltetrahydrofolate cyclohydrolase, putative.
 
  
 0.965
metH
Methionine synthase, putative; Contains B12 binding domains.
  
 
 0.956
purL
Phosphoribosylformylglycinamidine (fgam) synthase, purl component.
  
 
 0.953
HM1_1721
5-methyltetrahydrofolate--homocysteine s-methyltransferase, putative; Matches pterin binding enzyme domain, PF00809.
    
 0.948
purC
Phosphoribosylaminoimidazole-succinocarboxamide synthase; Belongs to the SAICAR synthetase family.
  
 
 0.837
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
  
  
 0.806
