Abstract:
A mutant prenyl diphosphate synthase having a modified amino acid sequence, wherein both an amino acid located at the fifth position upstream of D.sub.1 of the Asp-rich domain D.sub.1 D.sub.2 X.sub.1 (X.sub.2 X.sub.3)X.sub.4 D.sub.3 of conserved region II of prenyl diphosphate synthase and an amino acid located at the eighth position upstream of D.sub.1 of the Asp-rich domain D.sub.1 D.sub.2 X.sub.1 (X.sub.2 X.sub.3)X.sub.4 D.sub.3 of conserved region II of prenyl diphosphate synthase have each been substituted by another amino acid, wherein the mutant prenyl diphosphate synthase is capable of synthesizing a product having more than 30 carbon atoms.
