Abstract: The object of the present invention is to efficiently produce useful terpenoid compounds, and specifically, to provide a method for preparing squalene, which is an important intermediate of terpenoid. The object can be solved by a hydroxymethylglutaryl CoA reductase (HMGR) comprising:(a) an amino acid other than alanine (A) at the 10th position in an Sα2 amino acid sequence of HMGR, (b) an amino acid other than proline (P) at the 1st position from the carboxyl terminal in the DKK region of the HMG-CoA binding site of HMGR, (c) an amino acid other than alanine (A) at the 1st position in an Lα2 amino acid sequence of HMGR, and (d) an amino acid other than glutamic acid (E) at the 6th position in an Lα2 amino acid sequence of HMGR of the present invention.
