摘要:Disclosed are the following DNA strands relating to the synthesis of keto group-containing xanthophylls such as astaxanthin and the like, and the techniques relating to the production of xanthophylls by genetic engineering: A DNA strand having a nucleotide sequence which encodes a polypeptide having an enzyme activity for converting a methylene group at the 4-position of a beta -ionone ring into a keto group. A DNA strand having a nucleotide sequence which encodes a polypeptide having an enzyme activity for converting a methylene group at the 4-position of a 3-hydroxy- beta -ionone ring into a keto group. A DNA strand having a nucleotide sequence which encodes a polypeptide having an enzyme activity for adding a hydroxyl group to the 3-carbon of a 4-keto- beta -ionone ring. It is possible to produce a variety of xanthophylls such as canthaxanthin, astaxanthin and the like by introducing the DNA strands into an appropriate microorganism such as Escherichia coli and the like.

摘要:A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.

标 题 :Method for synthesis of aryl-carotenoids
发明人：CHENG QIONG; TAO LUAN; ROUVIERE PIERRE E
权利人:DU PONT
摘要:A method for the production of aryl-carotenoids is provided through bioconversion of cyclic carotenoids having at least one β-ionone ring. Expression of a heterologous gene encoding a carotene desaturase (crtU) enzyme in a host cell that produces a suitable cyclic carotenoid substrate effect the production of aryl carotenoids.

摘要:Disclosed in the present invention is a genetically-engineered Yarrowia lipolytica strain highly producing carotenoids, which is obtained by constructing a xylose-induced activation system in the genetically-engineered Yarrowia lipolytica strain XK17 to control the induced expression of critical enzymes for synthesis of astaxanthin, wherein the critical enzymes for synthesis of astaxanthin comprise β-carotene hydroxylase CrtZ and β-carotene ketonase CrtW. Further disclosed in the present invention is the use of the genetically-engineered Yarrowia lipolytica strain in fermentation production of carotenoids. The present invention starts from the Yarrowia lipolytica strain XK17 highly producing β-carotene, and uses the xylose-induced activation system to separately control the expressions of the β-carotene hydroxylase (CrtZ) and β-carotene ketonase (CrtW) or only control the expression of the CrtW or the CrtZ, thereby separately achieving highly producing astaxanthin, or canthaxanthin, or zeaxanthin under the functions of a proper xylose induction concentration and induction opportunity.
