ACC synthase is a critical enzyme in the ethylene biosynthesis pathway in plants, catalyzing the conversion of S-adenosylmethionine (SAM) to 1-aminocyclopropane-1-carboxylic acid (ACC), the immediate precursor of ethylene. This enzyme plays a pivotal role in regulating plant growth, development, and stress responses by controlling the levels of ethylene, a key plant hormone involved in processes like fruit ripening and response to environmental stressors.
