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

folCPutuative bifunctional Dihydrofolate/Folylpolyglutamate synthase; Citation: Bogner et al. (1987) J. Biol. Chem. 262:12337-12343; Alternative locus ID: PMED4_14691; Belongs to the folylpolyglutamate synthase family. (410 aa)    
Predicted Functional Partners:
folP
Putative 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.
 
 0.997
argD
N-acetylornithine aminotransferase; Alternative locus ID: PMED4_14681; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. ArgD subfamily.
  
  
 0.812
folK
Possible 2-amino-4-hydroxy-6-hydroxymethyldihydropteridine pyrophosphokinase; Citation: Talarico et al. (1992) J. Bacteriol. 174:5971-5977; Alternative locus ID: PMED4_02921.
  
  
 0.790
folB
Possible dihydroneopterin aldolase; Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin.
  
  
 0.790
folE
Putative GTP cyclohydrolase I; Citation: Katzenmeier et al. (1991) Biol. Chem. Hoppe-Seyler 372:991-997; Alternative locus ID: PMED4_05851.
  
  
 0.785
glyA
Serine hydroxymethyltransferase (SHMT); 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.
  
 0.705
fmt
Putative 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.
  
  
 0.675
ahcY,
Putative adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
     
 0.648
guaA
Glutamine amidotransferase class-I:GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
  
 0.639
serS
Seryl-tRNA synthetase; Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L- seryl-tRNA(Sec), which will be further converted into selenocysteinyl- tRNA(Sec).
