Retrotranscriptasas del VIH tipo 1 grupo O, activas a temperaturas elevadas

Abstract

La presente invención se encuadra dentro del campo de la biotecnología. Más concretamente, se refiere a retrotranscriptasas expresadas y purificadas en bacterias y que tienen la secuencia de aminoácidos de la retrotranscriptasa de un virus de la inmunodeficiencia humana de tipo 1 (VIH-1) del grupo O modificada en las posiciones 358, 359 y 360; y de variantes de esta enzima que contienen cambios adicionales en las posiciones 355 y 357 o en la 478 o en la posición 69 (en este caso acompañada de una inserción de dos aminoácidos). Estas polimerasas presentan mayor actividad que la enzima no mutada, a temperaturas elevadas (superiores a 60ºC). Además retienen capacidad de síntesis de ADN a temperaturas superiores a 70ºC. Por otro lado, la fidelidad de copia de estas enzimas no difiere significativamente de la presentada por la retrotranscriptasa no mutada.
