Abstract

La presente se relaciona con un polipéptido de xilanasa variante, o fragmento del mismo que tiene actividad de xilanasa, que comprende una o más modificaciones de aminoácidos de manera tal que el polipéptido o fragmento del mismo tiene una alterada sensibilidad a un inhibidor de xilanasa y tiene una alterada sensibilidad térmica, comparadas con la enzima xilanasa madre. Se proporciona secuencia nucleótidos que codifica dicho polipéptido variante y construcción de la misma. El campo de aplicación del polipéptido variante es el de ser útil en las áreas de horneado, procesamiento de cereales, producción de almidón, procesamiento de madera, en el realce del blanqueo de pulpa de madera.
