Abstract: | [EN] The present invention relates to a natural orange sesquiterpene synthase enzyme (CsTPS3) with δ-cadinene synthase activity, and also to the variants of said enzyme modified by the substitution of at least one amino acid that changes the catalytic activity thereof, converting said variants preferably into enzymes with elemol synthase activity or germacrene D synthase activity. A further subject matter of the present invention is the nucleic acid that encodes the natural CsTPS3 enzyme and also the modified versions derived therefrom, in addition to the gene constructs, expression vectors and bacterial strains that comprise same. The invention also relates to the use of these enzymes for synthesizing sesquiterpenes, preferably δ-cadinene, elemol and germacrene D, and provides a method for obtaining same. [ES] La presente invención se relaciona con un enzima natural sesquiterpeno sintasa de naranjo (CsTPS3) con actividad δ-cadineno sintasa, así como con las variantes de dicha enzima modificadas por la substitución de al menos un aminoácido que altera su actividad catalítica, transformándolas preferentemente en enzimas con actividad elemol sintasa o germacreno D sintasa. Son asimismo objeto de la presente invención, el ácido nucleico que codifica el enzima natural CsTPS3 así como las versiones modificadas derivadas de éste, además de las construcciones génicas, vectores de expresión y cepas bacterianas que los comprenden. La invención también se refiere al uso de estas enzimas para sintetizar sesquiterpenos, preferentemente δ-cadineno, elemol y germacreno D, y proporciona un método para la obtención de los mismos. |
