Alteration of the Catalytic Properties of Divinyl Ether Synthase as a Result of Substitutions of Unique Amino Acids

摘要

In plants, the lipoxygenase cascade and its products, oxylipins, play an important role in cell signaling and protection. The diversity of oxylipins is determined by the function of lipoxygenase and cyto-chromes P450 of the CYP74 family. There are three known types of CYP74 enzymes: two dehydrases (divinyl ether synthase (DES) and allene oxide synthase (AOS)) and one isomerase (hydroperoxide lyase (HPL)).
