Nostoc punctiforme (9Z,11E,13S)-13-hydroperoxy-9,11-octadecadienoate the ratio of (9Z,11E,13S)-13-hydroperoxy-9,11-octadecadienoate to (9Z,11E,13R)-13-hydroperoxy-9,11-octadecadienoate is higher than 80:20 at all pH values tested ?
additional information the enzyme also converts arachidonate to its (15S)-hydroperoxide. The enzyme shows no substrate preference Nostoc punctiforme ?
