CC -!- FUNCTION: Catalyzes the transfer of the phosphoribosyl group of 5-
CC phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'-
CC phosphoribosyl)-anthranilate (PRA). {ECO:0000255|HAMAP-Rule:MF_00211}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=diphosphate + N-(5-phospho-beta-D-ribosyl)anthranilate = 5-
CC phospho-alpha-D-ribose 1-diphosphate + anthranilate;
CC Xref=Rhea:RHEA:11768, ChEBI:CHEBI:16567, ChEBI:CHEBI:18277,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:58017; EC=2.4.2.18;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00211};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00211};
CC Note=Binds 2 magnesium ions per monomer. {ECO:0000255|HAMAP-
CC Rule:MF_00211};
CC -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC tryptophan from chorismate: step 2/5. {ECO:0000255|HAMAP-
CC Rule:MF_00211}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00211}.
CC -!- SIMILARITY: Belongs to the anthranilate phosphoribosyltransferase
CC family. {ECO:0000255|HAMAP-Rule:MF_00211}.
