ABSTRACT:
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 fromBrevundimonassp. strain SD-212. The β-ionone ring-4-ketolase gene and β-ionone ring-3-hydroxylase gene produced byBrevundimonassp. 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.
