This enzyme participates in aromatic amino acid biosynthesis and two-component system (general). (wikipedia.org)
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. (wikipedia.org)
It is a precursor for the aromatic amino acids phenylalanine and tyrosine,indole, indole derivatives and tryptophan,2,3-dihydroxybenzoic acid (DHB) used for enterobactin biosynthesis,the plant hormone salicylic acid and many alkaloids and other aromatic metabolites. (ecmdb.ca)

In enzymology, an anthranilate phosphoribosyltransferase (EC 2.4.2.18) is an enzyme that catalyzes the chemical reaction anthranilate + phosphoribosyl pyrophosphate ⇌ {\displaystyle \rightleftharpoons } N-(5-phosphoribosyl)-anthranilate + diphosphate The two substrates of this enzyme are anthranilate and phosphoribosyl pyrophosphate.
