Abstract
Un polipéptido que tiene actividad de lacasa que comprende una secuencia de aminoácidos que muestra al menos el 50 % de identidad con una secuencia de aminoácidos seleccionada del grupo que consiste en SEQ ID NO:3, SEQ ID NO:4 y SEQ ID NO:5, en el que un resto de glutamina está en una posición que se corresponde con la posición 386 de la secuencia de aminoácidos según SEQ ID NO:3.
Description
Las variantes de aminoácidos presentadas por estas mutaciones parecen ser únicas en posiciones correspondientes entre secuencias de polipéptidos relacionadas, ya que no se identificaron en una búsqueda de proteína en BLAST, un servicio de internet público que compara la secuencia de búsqueda con todas las secuencias depositadas en el dominio público. La búsqueda reveló algunas secuencias estrechamente relacionadas solo algunos aminoácidos diferentes de las búsquedas y un intervalo completo de secuencias homólogas con diferente grado de similitud (Tabla 1).
Tabla 1. Los resultados de la búsqueda con Blast
Las secuencias (números de acceso) se enumeran en el orden de similitud decreciente.

Con el fin de crear una imagen más general de la estructura de las secuencias relacionadas, se realizaron alineamientos múltiples de las secuencias reveladas. Se descargaron más de las 30 secuencias más similares que oscilaban del 98 al 50 % de identidad con las secuencias de búsqueda al software VectorNTI® (Invitrogen) y se
5 dispusieron en un alineamiento múltiple en el mismo orden que en la lista de BLAST (Figura 4). El alineamiento confirmó la naturaleza única de las presentes sustituciones de aminoácidos.
Pueden introducirse mutaciones correspondientes a la mutación Q386 y/o la mutación triple P487/W488/F489 mostrada en SEQ ID NO:3 a cualquiera de las secuencias de aminoácidos desveladas en el presente documento, u otras secuencias homólogas, por métodos convencionales conocidos en la técnica, tales como mutagénesis dirigida 10 al sitio, con el fin de mejorar su actividad de lacasa en condiciones alcalinas. Kits para realizar la mutagénesis dirigida al sitio están comercialmente disponibles en la técnica (por ejemplo, kit de mutagénesis dirigida al sitio QuikChange® II XL por Agilent Technologies). Métodos adecuados adicionales para introducir las mutaciones anteriores en un gen recombinante se desvelan, por ejemplo, en Methods in Molecular Biology, Vol 182, "In vitro mutagenesis protocols", Eds Jeff Braman, Humana Press 2002). Así, en el presente documento, se proporcionan 15 variantes de lacasa o mutantes que comprenden glutamina (Q) en una posición que se corresponde con la posición
