Useful mutations of bacterial alkaline protease

   
   

The present invention relates to mutations of a subtilisin gene which result in changes in the chemical characteristics of subtilisin enzymes. Mutations at specific nucleic acids of the subtilisin gene result in amino acid substitutions and consequently, altered enzyme function. Some of these mutant enzymes exhibit physical properties advantageous to industrial applications, particularly in the detergent industry, providing subtilisin which is more stable to oxidation, possesses greater protease activity, and exhibits improved washability.

La actual invención se relaciona con las mutaciones de un gene del subtilisin que dan lugar a cambios en las características químicas de las enzimas del subtilisin. Las mutaciones en los ácidos nucleic específicos del gene del subtilisin dan lugar a substituciones del aminoácido y por lo tanto, función alterada de la enzima. Algunas de estas enzimas del mutante exhiben las características físicas ventajosas a los usos industriales, particularmente en la industria detergente, proporcionando el subtilisin que es más estable a la oxidación, posee mayor actividad del protease, y exhibe washability mejorado.
