Catalyzes the formation of N-benzoylanthranilate, in the course of methoxydianthramide B, a phytoalexin. Phytoalexins are produced in response to infection by parasites, and are essential for the expression of disease resistance. anthranilate + benzoyl-CoA = CoA + N-benzoylanthranilate Inactive below pH 7.0. Phytoalexin biosynthesis; methoxydianthramide B biosynthesis. By fungal elicitors. Elicitation triggers a rapid, transient induction, reaching maximal abundances within about 0.5 hours and returning to basal levels within 4 hours. N-terminus is blocked. Belongs to the plant acyltransferase family.
