What is ALTRENOGEST?

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.

The Uses of ALTRENOGEST

Inhibitor of ethylene biosynthesis in plants.

The Uses of ALTRENOGEST

Inhibition of ethylene biosynthesis delays ripening of fruits in plants treated with AVG.
