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

folDMethenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate. (282 aa)    
Predicted Functional Partners:
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.
  
 0.981
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.
 
 
 0.979
purH
Similar to PUR9_RHIME (Q92KX6) Bifunctional purine biosynthesis purH from Rhizobium meliloti (536 aa). FASTA: opt: 1834 Z-score: 2200.5 E(): 1.1e-114 Smith-Waterman score: 1834; 55.344identity in 524 aa overlap Includes phosphoribosylaminoimidazolecarboxyamide formyltransferase and IMP synthetase.
  
 
 0.965
fmt
Methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
 
 
 0.962
purCD
Fusion protein PurC/PurD; Amino acids 1-327 (PurC) similar to AAR06292 SAICAR synthetase from Nicotiana tabacum (399 aa). BLAST: Expect = e-105 Identities = 187/322 (58), Positives = 236/322 (73), Gaps = 6/322 (1). Amino acids 328-770 (PurD) similar to ZP_00077753 Phosphoribosylamine-glycine ligase from Methanosarcina barkeri (433). BLAST: Expect = e-108 Identities = 204/436 (46), Positives = 285/436 (65), Gaps = 3/436 (0); Belongs to the GARS family.
  
  
 0.958
gcvT
Glycine cleavage complex protein T (aminomethyltransferase); The glycine cleavage system catalyzes the degradation of glycine.
  
 
 0.955
FTT_1220
5-formyltetrahydroformate cycloligase family protein; Similar to Q8ZM70 Putative ligase from Salmonella typhimurium (182 aa). FASTA: opt: 317 Z-score: 411.1 E(): 5.2e-15 Smith-Waterman score: 317; 32.727 identity in 165 aa overlap. ORF ftt1220; Belongs to the 5-formyltetrahydrofolate cyclo-ligase family.
  
 
 0.932
thyA
Thymidylate synthase; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by- product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis.
  
 
 0.926
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.
     
 0.901
purL
Modification methylase, pseudogene; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
