The invention relates to a method for producing derivatives of O-&#x3b1;-glucosylated flavonoid, comprising at least one step of incubating a glucansucrase with a flavonoid and at least one sucrose, the flavonoid being a flavonoid which is monohydroxylated or hydroxylated in a non-vicinal manner on the B cycle. The invention also relates to novel O-&#x3b1;-glucosylated flavonoid derivatives, and to the use thereof. 

Flavonoids O-A-glucosylated on the B cycle, method for the production thereof and uses

The invention relates to yeast cells modified to express a functional type I RuBisCO enzyme, and a class II phosphoribulokinase. The expression of these enzymes recreates a Calvin cycle in said yeasts in order to enable the yeasts to use carbon dioxide.

This invention relates to the production of 7-dehydrocholesterol, 25-hydroxy-7-dehydrocholesterol, and 25-hydroxy ergosterol in yeast such as. It also relates to various enzymes catalyzing the reduction of the double bond at position 24 of lanosterol, dimethyl zymosterol, methyl zymosterol, zymosterol, cholesta-7, 24-dienol, or cholesta-5,7,24-trienol; or the hydroxylation at position 25 of ergosterol, 7-dehydrocholesterol, cholesta-8-enol, and cholesta-7-enol. It also relates to various nucleic acids encoding cholesterol C25-hydroxylases and sterol &#x394;24-reductases and their use to produce and hydroxylate 7-dehydrocholesterol or ergosterol. It also relates to the yeast strains so produced, and methods of making these sterols that include the steps of cultivaton a transformed yeast cell, and harvesting the resulting sterol(s).

The present invention pertains to a supramolecular structure based on i-motif tetramers of C&#x2014;X&#x2014;Coligonucleotides, wherein m and n are integers comprised between 2 and 9, and X is a linker such as A, T, G, a modified deoxynucleotide or a diol spacer. These supramolecular structures can be dissociated, when necessary, by a mere pH change. The present invention also relates to methods for obtaining such a supramolecular structure.

Multidimensional supramolecular structures essentially made of assembled i-motif tetramers

The invention concerns the production of cholesterol of the Fungi kingdom. More particularly, the invention concerns genetically modified Fungus independently producing cholesterol from a simple carbon source. The invention also concerns the use of the inventive Fungus for producing non-marked and marked cholesterol.
