Allene oxide synthase-lipoxygenase protein

UniProtKB accession:  O16025

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Bifunctional enzyme which is responsible for allene oxide biosynthesis via a two-step reaction; first the lipoxygenase reaction that converts polyunsaturated fatty acids such as arachidonate ((5Z,8Z,11Z,14Z)-eicosatetraenoate) into a (8R)-hydroperoxide intermediate ((8R)-hydroperoxy-(5Z,9E,11Z,14Z)-eicosatetraenoate) followed by the allene oxide synthase reaction that converts the hydroperoxide intermediate ((8R)-hydroperoxy-(5Z,9E,11Z,14Z)-eicosatetraenoate) into the allene oxide (8,9-epoxy-(5Z,9E,11Z,14Z)-eicosatetraenoate) (PubMed:9302294, PubMed:10559269). Shows preference for C20 or C22 highly polyunsaturated fatty acids and no activity with C18 fatty acids in vitro (PubMed:10559269). Fatty acid allene oxides are intermediates in the formation of cyclopentenones or hydrolytic products in marine systems, most notably the prostanoid-related clavulones (PubMed:29909837).
