A method for transforming iota-carrageenan into alpha-carrageenan by a new class of 4S-iota-carrageenan sulfatase. The invention also relates to carrageenans obtained by the conversion method. The invention can be especially applied to the agro-food, pharmaceutical and cosmetic industries.

Method for transforming iota-carrageenan into alpha-carrageenan by means of a new class of 4S-iota-carrageenan sulfatase

The present invention relates to the isolation and to the characterization of two proteins having a novel enzymatic activity, i.e. a porphyranase activity. These proteins are useful for hydrolyzing polysaccharides containing sulfated agaro-colloids and for producing oligo-porphyrans, notably oligo-porphyrans with a defined structure and size.

Porphyranases, and use thereof for hydrolyzing polysaccharides

The present invention notably relates to ulvan lyases, to nucleic acid sequences coding for these ulvan lyases, to vectors comprising these coding sequences, to a method of manufacturing these ulvan lyases, as well as to a method of degrading ulvans using these ulvan lyases and applicable applications to the degradation products of the ulvans. The ulvan lyases of the present invention, or ulvanolytic protein, are notably defined as proteins of 30 or 46 kD comprising the following four sequences in their peptide sequence: PNDPNLK, LLEVGNTGTFGSTGS, DLANPDNV and WNLPE.

Ulvan lyase, method for manufacturing same, and uses thereof

The present invention relates to 4S-iota-carrageenan sulfatase and to the use thereof for partially or totally converting the iota-carrageenan into iota-/alpha-carrageenan or alpha-carrageenan. The invention also relates to the method for extracting said enzyme from abacteria population or from red marine algae. Finally, the present invention relates to the use of 4S-iota-carrageenan sulfatase to prepare a texturizing agent containing alpha-carrageenan.

4S-iota-carrageenan sulfatase and use thereof to obtain alpha-carrageenan

The invention relates to a ellulose film comprising microfibrillated cellulose and to the use of it for screening of a biological compound and nucleic acids encoding a biological compound.
