    摘要: Disclosed are the following DNA strands relating to the synthesis of keto group-containing xanthophylls such as astaxanthin and the like, and the techniques relating to the production of xanthophylls by genetic engineering: A DNA strand having a nucleotide sequence which encodes a polypeptide having an enzyme activity for converting a methylene group at the 4-position of .beta.-ionone ring into a keto group. A DNA strand having a nucleotide sequence which encodes a polypeptide having an enzyme activity for converting a methylene group at the 4-position of a 3-hydroxy-.beta.-ionone ring into a keto group. A DNA strand having a nucleotide sequence which encodes a polypeptide having an enzyme activity for adding a hydroxyl group to the 3-carbon of a 4-keto-.beta.-ionone ring. It is possible to produce a variety of xanthophylls such as canthaxanthin, astaxanthin and the like by introducing the DNA strands into an appropriate microorganism such as Escherichia coli and the like.

    摘要: To provide a microorganism or a plant transformed with a β-ionone ring-4-ketolase gene and/or β-ionone ring-3-hydroxylase gene derived from Brevundimonas sp. strain SD-212. The β-ionone ring-4-ketolase gene and β-ionone ring-3-hydroxylase gene produced by Brevundimonas sp. strain SD-212 each have a high activity compared with those of known enzymes, and therefore microorganisms transformed with the genes encoding these enzymes can efficiently produce astaxanthin.

    摘要: The production of carotenoid is accomplished using a DNA molecule that encodes a polypeptide as obtained from Haematococcus pluvialis, Phaffia rhodozyma, or Saccharomyces cerevisiae, having isopentonyl pyrophosphate (IPP) isomerase activity, or DNA molecule having a nucleotide sequence that hybridizes thereto. In particular, one can introduce such a DNA molecule into a carotenoid-producing microorganism, culture the microorganism thus transformed, and then obtain carotenoids in the culture broth and cells.

    摘要: An reproducible transformation system of a yeast of Candida utilis, a process for expressing a heterologous gene in the transformation system, a vector which can be used in the transformation system and the expression method, and a novel DNA group are disclosed. In particular, the process for expressing a heterologous gene in Candida utilis comprises transforming Candida utilis with a vector comprising a drug-resistance marker, a sequence homologous to the chromosomal DNA of the Candida utilis yeast, and the heterologous gene, culturing the transformant, and isolating the expression product of the heterologous gene.
