Abstract

SE PRESENTA UN PROCESO PARA CONVERTIR ALMIDON O ALMIDON PARCIALMENTE HIDROLIZADO EN UN SIROPE QUE CONTIENE DEXTROSA. EL PROCESO INCLUYE LOS PASOS DE SACARIFICAR HIDROCILATO DE ALMIDON EN LA PRESENCIA DE UNA GLUCOAMILASA MUTADA O ENZIMA RELACIONADA E INCREMENTAR LA SELECTIVIDAD DE LA ENZIMA PARA LOS ENLACES (ALFA)-(14)LACIONADA INCLUYENDO AL MENOS UNA MUTACION, SUBSTITUYENDO LA MUTACION A UN AMINOACIDO DE LA ENZIMA CON AL MENOS UN AMINOACIDO ESCOGIDO POR COMPARACION CON LAS REGIONES RELACIONADAS ESTRUCTURALMENTE DE OTRAS ENZIMAS QUE HIDROLICEN SELECTIVAMENTE LOS ENLACES (ALFA)-(1-4)GLUCOSIDICOS SOLAMENTE. TAMBIEN SE PRESENTAN ENZIMAS FABRICADAS DE ACUERDO CON LA INVENCION.
