Abstract

"PROCESSO PARA A PRODUçãO DE COMPOSTOS, SEQuêNCIA DE áCIDO NUCLEICO ISOLADA, SEQuêNCIA DE AMINOáCIDOS, CONSTRUçãO GêNICA, VETOR, E , ORGANISMO". A presente invenção refere-se a a um processo aperfeiçoado para a produção específica de ácidos graxos <sym>-3 e <sym>-6 poliinsaturados e a um processo para a produção de triglicerídeos apresentando um teor incrementado de ácidos graxos insaturados em particular ácidos graxos <sym>-3 e <sym>-6 apresentando pelo menos duas duplas ligações e um comprimento de cadeia de 20 ou 22 átomos de carbono. A invenção refere-se à produção de um organismo transgênico, de preferência uma planta transgênica ou um microorganismo transgênico, apresentando um teor incrementado de ácidos graxos, óleos ou lipídeos contendo ácidos graxos com C~ 20~ ou C~ 22~ com uma dupla ligação delta-5, 7, 8, 10, respectivamente devido à expressão de uma delta-8-desaturase e uma delta-9-elongase de organismos, como plantas, de preferência algas, como Isochrysis galbana ou Euglena gracilis. Adicionalmente, a invenção refere-se a um processo para a produção de acidos graxos poliinsaturados, como ácido eicosapentaenóico, araquidónico, docosapentaenóico ou docosaexaenóico por meio da co-expressão de uma delta-8-desaturase, uma delta-9-elongase e uma delta-5-desaturase em organismos, como microorganismos ou plantas. A invenção refere-se adicionalmente ao uso de seq³ências específicas de ácido nucleico codificando para as proteínas previamente indicadas com atividade de <30>-8desaturase, <30>-9-elongase ou <30>-5-desaturase, construções de ácido nucleico, vetores e organismos contendo referidas seq³ências de ácido nucleico. A invenção refere-se adicionalmente a ácidos graxos-insaturados e triglicerídeos apresentando um teor incrementado de pelo menos 1% em peso de ácidos graxos insaturados e ao uso dos mesmos.
