Enzyme Information

2.4.2.18

Anthranilate phosphoribosyltransferase.

based on mapping to UniProt P50384

N-(5-phospho-D-ribosyl)-anthranilate + diphosphate = anthranilate + 5-phospho-alpha-D-ribose 1-diphosphate.

-!- In some organisms, this enzyme is part of a multifunctional protein together with one or more components of the system for biosynthesis of tryptophan (EC 4.1.1.48, EC 4.1.3.27, EC 4.2.1.20 and EC 5.3.1.24).
