The present invention relates to methods and compositions related to the use of enzymes of the allene oxide synthase family for reducing myocardial ischemia reperfusion injury associated with myocardial infarction, thrombolysis, angioplasty and coronary bypass surgery. The methods of the invention comprise administration of allene oxide synthases, which are capable of eliminating lipid hydroperoxides, as a potent cardioprotective agent. The invention is based on the discovery that administration of allene oxide synthase following severe global ischemia stimulates cardiac recovery.

Guayule rubber particles, contain several characteristic proteins. The most abundant of these proteins, the rubber particle protein (RPP) has been shown to be a non-monooxygenase, cytochrome P450, heme-binding protein that is necessary for rubber biosynthesis. A full-length cDNA clone for guayule RPP has been isolated, sequenced and characterized. The pRPP30 coding sequence is transferable to other prokaryotic or eukaryotic host organisms wherein the RPP DNA will be expressed to produce functional RPP for rubber biosynthesis.

The present invention relates to the isolation and use of an allene oxide synthase enzyme as an antioxidant of lipid peroxides in biological systems. It is based, at least in part, on the discovery that antioxidation is accomplished enzymatically by RPP, a species of allene oxide synthase, in guayule, and on the discovery that the allene oxide synthase RPP disrupts the chain reaction and propagation steps of lipid peroxidation. The present further invention relates to the use of an allene oxide synthase to result in a time-dependent disappearance of conjugated dienes (i. e. lipid hydroperoxides). The allene oxide synthase rapidly converts free or esterified fatty acid peroxides or hydroperoxides into their corresponding epoxides, which, in turn are converted to ketols. The lipid peroxide and hydroperoxide substrates for this enzyme are known to be toxic to biological organisms and can generate additional peroxides by chain propagation reactions. In the presence of an allene oxide synthase these compounds are rapidly and effectively converted to allene oxides (the epoxide), thus breaking the chain reaction.
