The present invention relates to genes which code for glycosyl hydrolases having an HCA score with the iota-carrageenase of which is greater than or equal to 65% over the domain extending between amino acids 164 and 311 of the protein sequence SEQ ID No. 2 of said iota-carrageenase, and to genes which code for glycosyl hydrolases having an HCA score with the kappa-carrageenase of which is greater than or equal to 75% over the domain extending between amino acids 117 and 262 of the protein sequence SEQ ID No. 6 of said kappa-carrageenase.

Glycosyl hydrolase genes and their use for producing enzymes for the biodegradation of carrageenans

The invention concerns a medicine comprising, as active principle, an efficient quantity of at least an oligosaccharide substance capable of modulating apoptosis dysfunction which is capable of modifying apoptosis dysfunctions said substance being selected from the group consisting of oligosaccharides which are derived, by enzymatic or chemical process, from the polymers of the group comprising (1&rarr;3)-&bgr;-glucans which optionally comprise (1&rarr;6)-&bgr;-branching, and oligosaccharides which are derived, by enzymatic or chemical process, from sulfated galactans, it also concerns a method for treating apoptosis dysfunction.

Medicine for treating apoptosis dysfunction containing oligosaccharides

The present invention provides a method to potentiate and stimulate natural defensive reactions of plants to a pathogenic agent. The method comprises application to plants of a composition comprising an effective amount of one or more oligo &bgr; 1-3 glucans composed of 3 to 250 monosaccharide units and a vehicle, wherein the effective amount of oligo &bgr; 1-3 glucans in the composition does not directly stimulate natural defensive reactions of plants when the pathogenic agent is absent.

Method for stimulating natural control system of plants

The present invention relates to genes which code for glycosyl hydrolases having an HCA score with the iota-carrageenase of,which is greater than or equal to 65% over the domain extending between amino acids 164 and 311 of the protein sequence SEQ ID No. 2 of said iota-carrageenase, and to genes which code for glycosyl hydrolases having an HCA score with the kappa-carrageenase of,which is greater than or equal to 75% over the domain extending between amino acids 117 and 262 of the protein sequence SEQ ID No. 6 of said kappa-carrageenase.
