Abstract

Patente de Invenção: <B>"FITASES MODIFICADAS"<D>. A presente invenção refere-se a um processo para a produção de uma fitase modificada com propriedades de atividades aperfeiçoadas, caracterizada pelo fato de que são efetuadas as seguintes etapas: a) a estrutura tridimensional da fitase a ser modificada e, opcionalmente, de outra fitase com propriedades de atividade que são mais favoráveis do que aquelas da fitase a ser modificada, é/são modelada(s) em computador com base na estrutura tridimensional da fitase de <MU>Aspergillus niger<MV>; b) a estrutura dos sítios ativos da fitase a ser modificada e da fitase com as propriedades de atividades mais favoráveis são comparadas e aqueles resíduos de aminoácidos em ambos os sítios ativos que sejam diferentes são identificados; c) uma seq³ência de ADN que codifica uma fitase modificada é construída modificando-se os nucleotídeos que codificam pelo menos um dos aminoácidos pelos quais ambos os sítios ativos se diferem; d) integrar uma tal seq³ência de ADN em um vetor capaz de expressão em uma célula de hospedeiro adequada; e) transformar uma célula de hospedeiro adequada pela seq³ência de ADN de c) ou o vetor d), crescer a dita célula de hospedeiro sob condições de crescimento adequadas e isolar a fitase modificada a partir da célula de hospedeiro ou do meio de cultura por processos conhecidos no estado da técnica. A presente invenção refere-se ainda à fitase modificada obtida ou obtenível por tal processo, à seq³ência de ADN que codifica esta fitase, ao vetor que compreende tal seq³ência de ADN, à célula de hospedeiro transformada por tal seq³ência de ADN e a um alimento ou composição alimentícia compreendendo esta fitase.
