    1-aminocyclopropane-1-carboxylate synthase (ACS) is a key enzyme in the biosynthesis of the plant hormone ethylene. Recently, a new biological role for ACS has been found in Cucumis melo where a single point mutation (A57V) of one isoform of the enzyme, causing reduced activity, results in andromonoecious plants. We present here a straightforward structural basis for the reduced activity of the A57V mutant, based on our work on Malus domestica ACS, including a new structure of the unliganded apple enzyme at 1.35Å resolution.
