Title (EN) IMPROVEMENT IN ENZYME STABILITY
(FR) AMELIORATION DE LA STABILITE D'ENZYMES
Abstract: front page image
(EN)The invention relates to an enzyme and processes for producing an enzyme capable of cleaving $g(b)-1,4-xylosidic bonds of xylan. The enzyme comprises a xylanase which has been modified by having an uncharged or positively-charged molecule linked to a side chain of an amino acid of the xylanase and/or to a carboxy-terminal amino acid of the xylanase. The enzyme functions at an elevated temperature and/or has an extended half-life compared to the corresponding unmodified xylanase.
(FR)Cette invention porte sur une enzyme et sur des procédés de production d'une enzyme pouvant effectuer le clivage de liaisons $g(b)-1,4-xylosidiques de xylane. Cette enzyme comprend une xylanase qui a été modifiée par l'introduction d'une molécule neutre ou chargée positivement liée à une chaîne latérale d'un acide aminé de la xylanase et/ou à un acide aminé C-terminal de la xylanase. L'enzyme agit à une température élevée et/ou présente une demi-vie prolongée par rapport à la xylanase non modifiée correspondante.
