Insights from the X-ray crystal structure of coral 8R-lipoxygenase: calcium activation via A C2-like domain and a structural basis of product chirality
2fnq is a 2 chain structure with sequence from Plexaura homomalla. This structure supersedes the now removed PDB entry 1zq4. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
AOSL_PLEHO Bifunctional enzyme which is responsible for allene oxide biosynthesis via a two-step reaction which involves conversion of arachidonic acid to a 8R-hydroperoxide intermediate followed by conversion of the hydroperoxide to allene oxide.[1][2]
