    摘要: DNA sequences are described that encode genes for synthesizing ketocarotenoids such as astaxanthin. The DNA sequences, microorganisms containing them and encoded polypeptides are described. Also described are methods to obtain related sequences and to make host cells that contain such sequences. These genes and methods are useful to impart red coloration during culture of fish and crustaceans, as coloring in food, and as antioxidants.

    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.
