The present invention provides a prenyl diphosphate synthetase and a gene coding for the synthetase. The invention discloses a recombinant protein having the amino acid sequence shown in SEQ ID NO:2 or a recombinant protein which has the amino acid sequence shown in SEQ ID NO:2 having deletion, substitution or addition of at least one amino acid and which has decaprenyl diphosphate synthetase activity; a gene coding for the protein; a recombinant vector comprising the gene; a transformant transformed with the vector; a method for producing a decaprenyl diphosphate synthetase; and a method for producing ubiquinone-10.

Decaprenyl diphosphate synthetase gene

The present invention provides a polypeptide selected from a polypeptide of subunit (A) or a polypeptide of subunit (B) of a prenyl diphosphate synthetase; a DNA coding for the polypeptide; a recombinant vector comprising the DNA; a transformant transformed with the vector; and a method for preparing an active type prenyl diphosphate synthetase. Also disclosed is a method for preparing an active type enzyme on which a specific property has been conferred, comprising mixing polypeptides of the two subunits of a heterodimeric enzyme, the polypeptides being derived from different organisms and one of the polypeptides having the specific property.

Method of making recombinant enzyme

Heptaprenyl diphosphate (HDP)-synthetase derived from Bacillus stearothermophilus which enzymes have the amino acid sequences shown as SEQ ID NOs: 1 to 3; 1 and 2; 2 and 3; or 1 and 3, DNA encoding them, and a method of producing the enzymes. According to the invention it is possible to industrially produce HDP-synthesizing enzyme and HPD.

Heptaprenyl diphosphate-synthetase

A DNA sequence that encodes a stable farnesyl pyrophosphate synthetase and the use thereof are provided. DNA sequence that encodes a farnesyl pyrophosphate synthetase originating from Bacillus stearothermophilus is provided. By selecting Bacillus stearothermophilus as the gene origin of the synthetase, a production system for the synthetase, a production system for the synthetase particularly having thermal stability, can be constructed.
