Keto group introducing enzyme, dna coding for the same, and process for producing ketocarotenoid |
| abstract |
A polypeptide having the enzymatic activity of converting the 4-methylene group of a β-ionone compound into a keto group; a DNA containing the base sequence coding for the above polypeptide; another DNA which hybridizes with the above DNA and contains the base sequence coding for the above polypeptide; still another DNA which has been inserted into plasmid pHP51 and contains the base sequence coding for the above polypeptide; a recombinant vector containing the above DNA(s); a microbe having the above DNA(s) introduced thereinto; and a process for producing a ketocarotenoid which comprises culturing the above microbe in a medium and separating the formed ketocarotenoid from the product of culture. The introduction of the above DNAs as foreign genes into microbes, such as E. coli , followed by expression thereof makes it possible to impart to the microbes the capability of biosynthesis of astaxanthin, 4-ketozeaxanthin, canthaxanthin, echinenone and other ketocarotenoids. The use of such microbes makes it possible to mass-produce ketocarotenoids at reduced cost and labor. |
