context_page_description: In enzymology, an anthranilate phosphoribosyltransferase is an enzyme that catalyzes the chemical reaction
  anthranilate + 5-phospho-alpha-D-ribose 1-diphosphate N--anthranilate + diphosphate
  Thus, the two substrates of this enzyme are anthranilate and 5-phospho-alpha-D-ribose 1-diphosphate, whereas its two products are N--anthranilate and diphosphate.
  This enzyme participates in aromatic amino acid biosynthesis and two-component system.
context_section_description: In the aromatic amino acid biosynthesis pathway specifically the tryptophan synthesis portion, AnPRT draws anthranilate and 5-phospho-alpha-D-ribose 1-diphosphate into the active site of the protein. Through the Sn1 mechanism below, AnPRT transfers the 5-phospho-alpha-D-ribose group (shown in blue) to the anthranilate (shown in red) from the diphosphate molecule (shown in black).
