    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.

    Abstract: A transparentization agent composition is a mixture containing 100 parts by mass of a dibenzylidene sorbitol compound represented by a general formula (I) having a particle diameter such that d97 is from 30 μm to 200 μm and 5 to 200 parts by mass of tetrakis[3(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl]methane, wherein the total for the two components is 50% by mass or more of the mixture. Also disclosed is a method for producing a polypropylene resin composition, including obtaining a polypropylene resin composition in which a dibenzylidene sorbitol compound represented by a general formula (I) having a particle diameter such that d97 is from 30 μm to 200 μm is incorporated in a polypropylene resin, by kneading a mixture containing 100 parts by mass of the polypropylene resin and 0.05 to 2 parts by mass of the dibenzylidene sorbitol compound by using a biaxial extruder at an extrusion temperature of from 220 to 250° C.
