Abstract
Isolated gene cluster involved in canthaxanthin biosynthesis, which comprises a polynucleotide wherein: crtY, crtI, crtB and crtW genes are clustered in this order and in the same orientation, and, preceding the four cited genes, crtE gene is oriented in the opposite direction. Applications for producing natural carotenoids useful in pharmaceutical, cosmetic and nutritious compositions.
Claims12
An isolated gene cluster comprising an isolated polynucleotide wherein:
- crtY, crtI, crtB and crtW genes are clustered in this order and in the same orientation, and,
- preceding the four cited genes, crtE gene is oriented in the opposite direction, said crtW gene of the polynucleotide being SEQ ID NO:1, and
- said crtY, crtE, crtB and crtI genes of the polynucleotide being SEQ ID NO:2 to SEQ ID NO:5, respectively.
An isolated polynucleotide consisting of SEQ ID NO:1.
An isolated gene cluster comprising one of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4, and SEQ ID NO:5.
