Comments [?]

Function Catalyzes the transfer of the phosphoribosyl group of 5-phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'-phosphoribosyl)-anthranilate (PRA).
Catalytic activity RHEA:11768: diphosphate + N-(5-phospho-beta-D-ribosyl)anthranilate = 5-phospho-alpha-D-ribose 1-diphosphate + anthranilate
EC 2.4.2.18
Cofactor Mg(2+)
Note: Binds 2 magnesium ions per monomer.
Pathway Amino-acid biosynthesis; L-tryptophan biosynthesis; L-tryptophan from chorismate: step 2/5.
Subunit Homodimer.
Similarity Belongs to the anthranilate phosphoribosyltransferase family.
