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

sulADihydropteroate synthase; Catalyzes the condensation of para-aminobenzoate (pABA) with 6-hydroxymethyl-7,8-dihydropterin diphosphate (DHPt-PP) to form 7,8- dihydropteroate, the immediate precursor of folate derivatives. (314 aa)    
Predicted Functional Partners:
sulB
Dihydrofolate synthetase; Belongs to the folylpolyglutamate synthase family.
 
 0.999
sulD
Aldolase-pyrophosphokinase; Catalyzes two sequential steps of tetrahydrofolate biosynthesis, the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin diphosphate. In the N-terminal section; belongs to the DHNA family.
 
 0.999
sulC
GTP cyclohydrolase.
  
 0.995
folC
Dihydrofolate:folylpolyglutamate synthetase; Belongs to the folylpolyglutamate synthase family.
 
 0.992
pabB
Para-aminobenzoate synthetase.
 
 
 0.976
dfr
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
  
  
 0.963
pbpX
Penicillin-binding protein 2X; Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis. Beta-lactams inactivate the PBPs by acylating an essential serine residue in the active site of these proteins.
  
  
 0.685
imdH
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
  
 0.638
trpG
Anthranilate synthase component II (glutamine amido-transferase).
 
  
 0.623
pbp2b
Penicillin-binding protein 2B.
  
  
 0.604
