Abstract

S-adenosylmethionine (SAM) acts both as a precursor for the production of ethylene and as a substrate in the biosynthesis of polyamines. The conversion of SAM to 1-aminocyclopropane-1-carboxylic acid (ACC) is a key regulatory step in the biosynthesis of ethylene and is catalyzed by the enzyme ACC synthase (ACS), which is encoded by a multi-gene family in plants. The various ACS isoforms have diverse properties, both in terms of biochemical characteristics and regulated turnover in vivo.Here, the characteristics of the ACS gene families and the encoded proteins in various plant species, as well as the synthesis and role of polyamines and the flow of SAM into these two pathways, are discussed.
