摘要

A mutant protein obtained by mutating an hmgr-specific amino acid residue, an enzyme limiting the isoprene biosynthesis rate in the polyisoprenoid biosynthesis pathway, is provided. The present invention relates to a mutant protein wherein at least one amino acid residue selected from the group consisting of amino acid residues at positions 91, 225, 257, 287, 339, 411, 470, 509 and 574 of Arabidopsis thaliana 3-hydroxy-3-methylglutaryl coa reductase shown by sequence: 1 and amino acid residues at the positions corresponding to those mentioned above in 3-hydroxy-3-methylglutaryl coa reductase is deleted or replaced by another amino acid.
