WebFeb 22, 2024 · The ethylene biosynthetic pathway and ACC conjugation process. In this pathway methionine is converted to S-adenosyl methionine (SAM) by the enzyme SAM synthase. SAM is converted to ACC (1-aminocyclopropane-1-carboxylate) and 5-methylthioadenosine (MTA), by the enzyme ACC synthase. ... Regulation of ethylene … WebEthylene is synthesized in flowering plants from methionine via a cyclic pathway, which preserves the methylthio group of methionine while using ATP. Two notable intermediates in the cycle are S-adenosyl-methionine and 1-aminocyclopropane-l-carboxylic acid; the latter compound is the immediate precursor of ethylene.
