Enzyme Information

4.1.3.27
Anthranilate synthase.
based on mapping to UniProt P00897
Chorismate + L-glutamine = anthranilate + pyruvate + L-glutamate.
-!- 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 2.4.2.18, EC 4.1.1.48, EC 4.2.1.20 and EC 5.3.1.24). -!- The native enzyme in the complex with uses either glutamine or (less efficiently) NH(3). -!- The enzyme separated from the complex uses NH(3) only.
