Allene oxide cyclase (AOC) catalyzes the stereospecific cyclization of an unstable allene oxide to (9S,13S)-12-oxo-(10,15Z)-phytodienoic acid, which is the precursor next to jasmonic acid. Since the dimeric enzyme is found with two identical N-terminal peptides, the allene oxide cyclase is suggested to be a homodimeric protein assembled through processed N-termination. The homology among the AOC of Bruguiera sexangula (Lour.) Pair and Lycopersicon and Arabidopsis is very high, however, the AOC of Bruguiera ...
