1 -Aminocyclopropanecarboxylic acid ethylene biosynthesis

Selectively deuterated 1-aminocyclopropanecarboxylic acid ACC 71 was prepared to investigate the biosynthesis of ethylene in plants [105 a] and of ammonia and 2-ketobutyrate in Pseudomonas [105bj. 

The continuing interest in the role of aminocyclopropanecarboxylic acids in ethylene biosynthesis has resulted in the development of large scale routes to deuterium-labelled coronamic acid analogues [e.g. (485) and... 

The biosynthesis begins from methionine (63 see Chapter 27) with 1-amino-cyclopropane-l-carboxylic acid (64, ACC see Chapter 28) as a key intermediate. ACC oxidase aminocyclopropanecarboxylate oxidase) is involved in the last step of ethylene biosynthesis. ACC oxidase is an enzyme that catalyzes ethyleneforming reactions.
