The enzyme acetylajmaline esterase (EC 3.1.1.80, AAE, 2β(R)-17-O-acetylajmalan:acetylesterase, acetylajmalan esterase; systematic name 17-O-acetylajmaline O-acetylhydrolase){{cite journal | vauthors = Polz L, Schübel H, Stöckigt J | title = Characterization of 2β(R)-17-O-acetylajmalan: acetylesterase--a specific enzyme involved in the biosynthesis of the Rauwolfia alkaloid ajmaline | journal = Zeitschrift für Naturforschung C | volume = 42 | issue = 4 | pages = 333–42 | date = April 1987 | pmid = 2955586 }}{{cite journal | vauthors = Ruppert M, Woll J, Giritch A, Genady E, Ma X, Stöckigt J | title = Functional expression of an ajmaline pathway-specific esterase from Rauvolfia in a novel plant-virus expression system | journal = Planta | volume = 222 | issue = 5 | pages = 888–98 | date = November 2005 | pmid = 16133216 | doi = 10.1007/s00425-005-0031-0 }} catalyses the following reactions:

: (1) 17-O-acetylajmaline + H₂O $\backslash rightleftharpoons$ ajmaline + acetate

: (2) 17-O-acetylnorajmaline + H₂O $\backslash rightleftharpoons$ norajmaline + acetate

This plant enzyme mediates the last stages in the biosynthesis of the indole alkaloid ajmaline.
