Description
Ethylene, an important plant regulator, is synthesized from S-
adenosyl-
L-
methionine by the sequential action of 1-
amino-
cyclopropane-
carboxylate (ACC) synthases (ACSs) and ACC oxidases (ACOs). Aminoethoxyvinyl glycine is an inhibitor of ethylene biosynthesis that, at 1 μM, blocks the activity of both ACSs and ACOs. Through this action, it reduces ethylene-
mediated changes in plant growth and development. Aminoethoxyvinyl glycine also inhibits cystathionine γ-
lyase (K
i = 10.5 μM) with slow-
and tight-
binding characteristics.
Biochem/physiol Actions
(S)-trans-2-Amino-4-(2-aminoethoxy)-3-butenoic acid hydrochloride, is an ethylene synthesis inhibitor. It is used to study the roles of ethylene in plant processes such as gravitropism and fasciation/cresting.
