Scope note: Grupo de enzimas que catalizan la hidrólisis de los enlaces xilosídicos alfa o beta. EC 3.2.1.8 cataliza la endohidrólisis de los enlaces 1,4-beta-D-xilosídicos; EC 3.2.1.32 cataliza la endohidrólisis de los enlaces 1,3-beta-D-xilosídicos; EC 3.2.1.37 cataliza la exohidrólisis de los enlaces 1,4-beta-D a partir de las terminaciones no reductoras de los xilanos; y EC 3.2.1.72 cataliza la exohidrólisis de los enlaces 1,3-beta-D a partir de las terminaciones no reductoras de los xilanos. Se han identificado otras xilosidasas que catalizan la hidrólisis de los enlaces alfa-xilosídicos.

Scope note: A group of enzymes that catalyze the hydrolysis of alpha- or beta-xylosidic linkages. EC 3.2.1.8 catalyzes the endo-hydrolysis of 1,4-beta-D-xylosidic linkages; EC 3.2.1.32 catalyzes the endo-hydrolysis of 1,3-beta-D-xylosidic linkages; EC 3.2.1.37 catalyzes the exo-hydrolysis of 1,4-beta-D-linkages from the non-reducing termini of xylans; and EC 3.2.1.72 catalyzes the exo-hydrolysis of 1,3-beta-D-linkages from the non-reducing termini of xylans. Other xylosidases have been identified that catalyze the hydrolysis of alpha-xylosidic bonds.
