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

fhs-2Formate--tetrahydrofolate ligase; Identified by match to protein family HMM PF01268; Belongs to the formate--tetrahydrofolate ligase family. (557 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.
 
 
 0.997
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.
  
 0.979
SGO_1807
Serine cycle enzyme, putative; Identified by match to protein family HMM PF04961.
    
 0.965
purH
Bifunctional purine biosynthesis protein PurH; Identified by match to protein family HMM PF01808; match to protein family HMM PF02142; match to protein family HMM TIGR00355.
  
 0.961
ftcD
Glutamate formiminotransferase; Identified by match to protein family HMM PF02971; match to protein family HMM PF07837; match to protein family HMM TIGR02024.
    
  0.958
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.
  
 0.948
folA
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
  
 
 0.911
SGO_0035
Phosphoribosylformylglycinamidine synthase; Identified by match to protein family HMM PF01965; match to protein family HMM PF02769; match to protein family HMM TIGR01857.
  
 
 0.908
fhs-1
Formate--tetrahydrofolate ligase; Identified by match to protein family HMM PF01268; Belongs to the formate--tetrahydrofolate ligase family.
  
  
 
0.902
hutH
Histidine ammonia-lyase; Identified by match to protein family HMM PF00221; match to protein family HMM TIGR01225; Belongs to the PAL/histidase family.
