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

folEGTP cyclohydrolase I; Protein involved in folic acid biosynthetic process; Belongs to the GTP cyclohydrolase I family. (222 aa)    
Predicted Functional Partners:
folK
7,8-dihydro-6-hydroxymethylpterin- pyrophosphokinase; Protein involved in folic acid biosynthetic process; Belongs to the HPPK family.
  
 0.999
queD
6-pyruvoyl tetrahydrobiopterin synthase (PTPS); Catalyzes the conversion of 7,8-dihydroneopterin triphosphate (H2NTP) to 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) and acetaldehyde. Can also convert 6-pyruvoyltetrahydropterin (PPH4) and sepiapterin to CPH4; these 2 compounds are probably intermediates in the reaction from H2NTP.
  
 
 0.998
folX
D-erythro-7,8-dihydroneopterin triphosphate 2'-epimerase and dihydroneopterin aldolase; Catalyzes the epimerization of carbon 2' of the side chain of 7,8-dihydroneopterin triphosphate (H2NTP) to form 7,8-dihydromonapterin triphosphate (H2MTP). Is required for tetrahydromonapterin biosynthesis, a major pterin in E.coli.
 
 
 0.992
folP
7,8-dihydropteroate synthase; Catalyzes the condensation of para-aminobenzoate (pABA) with 6-hydroxymethyl-7,8-dihydropterin diphosphate (DHPt-PP) to form 7,8- dihydropteroate (H2Pte), the immediate precursor of folate derivatives. Belongs to the DHPS family.
 
  
 0.991
ribA
GTP cyclohydrolase II; Catalyzes the conversion of GTP to 2,5-diamino-6- ribosylamino-4(3H)-pyrimidinone 5'-phosphate (DARP), formate and pyrophosphate.
 
 
 
 0.986
folB
Dihydroneopterin aldolase and dihydroneopterin triphosphate 2'-epimerase; Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin. Can use L-threo-dihydroneopterin and D-erythro-dihydroneopterin as substrates for the formation of 6- hydroxymethyldihydropterin, but it can also catalyze the epimerization of carbon 2' of dihydroneopterin to dihydromonapterin at appreciable velocity; Belongs to the DHNA family.
 
  
 0.976
nudB
Dihydroneopterin triphosphate pyrophosphatase; Catalyzes the hydrolysis of dihydroneopterin triphosphate to dihydroneopterin monophosphate and pyrophosphate. Required for efficient folate biosynthesis. Can also hydrolyze nucleoside triphosphates with a preference for dATP.
  
 
 0.942
queE
7-carboxy-7-deazaguanine synthase; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.
  
  
 0.940
queC
7-cyano-7-deazaguanine (preQ0) synthase; Catalyzes the ATP-dependent conversion of 7-carboxy-7- deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)).
     
 0.931
folC
Bifunctional folylpolyglutamate synthase/ dihydrofolate synthase; Functions in two distinct reactions of the de novo folate biosynthetic pathway. Catalyzes the addition of a glutamate residue to dihydropteroate (7,8-dihydropteroate or H2Pte) to form dihydrofolate (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also catalyzes successive additions of L-glutamate to tetrahydrofolate or 10- formyltetrahydrofolate or 5,10-methylenetetrahydrofolate, leading to folylpolyglutamate derivatives.
