  • Carotenoid hydroxylase gene, method for preparing hydroxylated carotenoid, and novel geranylgeranyl pyrophosphate synthase
    Patent number: 7695931
    Abstract: The present invention provides a Brevundimonas sp. strain SD212-derived peptide having ?-ionone ring-2-hydroxylase activity and a gene encoding the same, to thereby make it possible to produce rare carotenoids in which a hydroxyl group is introduced at the position 2(2?) carbon in their ?-ionone ring in large quantities. The present invention also provides a novel gene encoding an enzyme which introduces a hydroxyl group at the position 3(3?) carbon in the ?-ionone ring of carotenoids, and a novel gene encoding a geranylgeranyl pyrophosphate synthase.
