カロテノイド合成微生物の作製方法およびカロテノイドの製造方法

Document Type and Number:

Japanese Patent JP5023474

Kind Code:

B2

Abstract:

To prepare a microorganism capable of producing carotenoid in an industrial scale and provide a carotenoid produced by using a new carotenoid-producing strain.

A carotenoid is prepared by using a cell transformed with a DNA sequence encoding a polypeptide having a specific enzymatic activity of (a) to (f) and derived from Paracoccus sp. MBIC1143 strain or a DNA sequence essentially homologous to the above DNA sequence or a cell transformed by a vector having the above DNA sequence; (a) enzymatic activity to convert the 4-methylene group of a β-ionone ring to keto group, (b) enzymatic activity to add one hydroxyl group to the 3 carbon of 4-keto-βionone ring or to the 3 carbon of β-ionone ring, (c) enzymatic activity to convert lycopene to β-carotene, (d) enzymatic activity to convert phytoene to lycopene, (e) prephytoene synthetase activity and (f) geranylgeranyl diphosphate synthase activity.
