Abstract

Una enzima xilanasa de la Familia 11 es seleccionada del grupo que comprende las xilanasas de la Familia 11 de Trichoderma, Aspergillus,Streptomyces y Bacillus que poseen el aminoácido tirosina o fenilalanina en la posicion 14 determinado segun la numeracion de aminoácidos de la xilanasaII de Trichoderma reesei o en la posicion correspondiente en las otras xilanasas cuando se alinean los aminoácidos y que poseen por lo menos 8residuos aminoacídicos en el N-terminal hacia elextremo 5 desde la posicion 10, habiendo dicha enzima xilanasa sido modificada para presentar mayorafinidad por la temperatura, mayor afinidad por álcalis o termoestabilidad con respecto a la enzima natural por sustitucion del aminoácido en la posicion10 con un aminoácido diferente. Asimismo, se protegen los métodos mencionados previamente.
