(57) [Problem] To provide a gene and an enzyme involved in the final step of an astaxanthin biosynthesis pathway from β-carotene to astaxanthin. SOLUTION: The present invention provides genetic material useful for preparation of astaxanthin from β-carotene, such as a polypeptide having astaxanthin synthase activity, a DNA fragment encoding astaxanthin synthase, and a recombinant organism. These new genetic materials may be from Phaffia rhodozyma. Also provided is a method for producing astaxanthin. |
