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

SGO_1913Dihydrofolate synthetase; Identified by match to protein family HMM PF02875; match to protein family HMM PF08245; match to protein family HMM TIGR01499; Belongs to the folylpolyglutamate synthase family. (444 aa)    
Predicted Functional Partners:
folP
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.
 
 0.998
SGO_1912
Bifunctional folate synthesis protein; Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin.
 
  
 0.975
SGO_2039
Dihydrofolate synthase; Identified by match to protein family HMM PF02875; match to protein family HMM PF08245; match to protein family HMM TIGR01499; Belongs to the folylpolyglutamate synthase family.
  
  
 
0.916
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
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.
     
 0.823
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
  
 0.612
SGO_1915
Abortive infection protein; Identified by match to protein family HMM PF02517.
       0.568
SGO_0348
Reductase.
     
 0.530
SGO_1909
Membrane protein, putative.
       0.529
SGO_1910
Membrane protein, putative.
