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.

folPDihydropteroate 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. (285 aa)    
Predicted Functional Partners:
folB
Dihydroneopterin aldolase; Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin.
 
 0.999
folK
7,8-dihydro-6-hydroxymethylpterin pyrophosphokinase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the HPPK family.
 
 0.999
folC
Folyl-polyglutamate 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, leading to folylpolyglutamate derivatives.
 
 0.999
pabC
4-amino-4-deoxychorismate pyruvate-lyase; Involved in the biosynthesis of p-aminobenzoate (PABA), a precursor of tetrahydrofolate. Converts 4-amino-4-deoxychorismate into 4-aminobenzoate (PABA) and pyruvate (By similarity).
  
 
 0.998
folEA
GTP cyclohydrolase I; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the GTP cyclohydrolase I family.
  
 0.998
pabA
4-amino-4-deoxychorismate synthase; Part of a heterodimeric complex that catalyzes the two-step biosynthesis of 4-amino-4-deoxychorismate (ADC), a precursor of p- aminobenzoate (PABA) and tetrahydrofolate. In the first step, a glutamine amidotransferase (PabA) generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by aminodeoxychorismate synthase (PabB) to produce ADC. PabA converts glutamine into glutamate only in the presence of stoichiometric amounts of PabB. Also involved in the biosynthesis of anthranilate.
 
  
 0.964
dfrA
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis (By similarity).
  
  
 0.946
pabB
4-amino-4-deoxychorismate synthase (para-aminobenzoate synthase); Part of a heterodimeric complex that catalyzes the two-step biosynthesis of 4-amino-4-deoxychorismate (ADC), a precursor of p- aminobenzoate (PABA) and tetrahydrofolate. In the first step, a glutamine amidotransferase (PabA) generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by aminodeoxychorismate synthase (PabB) to produce ADC.
 
  
 0.941
yazB
Putative transcriptional regulator; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pr: putative regulator.
  
    0.916
dusB
tRNA-dihydrouridine synthase B; Catalyzes the synthesis of 5,6-dihydrouridine (D), a modified base found in the D-loop of most tRNAs, via the reduction of the C5-C6 double bond in target uridines; Belongs to the Dus family.
