Expressed in all tissues but weaker in the columella. Expression gets weaker in more mature parts, especially in outer tissues.
Catalyzes the first step of tryptophan biosynthesis: Chorismate L-Glutamine = Anthranilate Pyruvate L-Glutamate. Functions as a heterocomplex with anthranilate synthase alpha subunit (ASA1 or ASA2).
ASB1 (ANTHRANILATE SYNTHASE BETA SUBUNIT 1); anthranilate synthase
