  • DNA having genetic information of L-.alpha.-glycerophosphate oxidase and application thereof
    Patent number: 4960877
    Abstract: DNA having a base sequence encoding a specified amino acid sequence of a polypeptide constituting an L-.alpha.-glycerophosphate oxidase (GPO) is disclosed. A polypeptide having the specified amino acid sequence can be produced by inserting the DNA into a plasmid, culturing a transformant produced by introducing this plasmid into a host microorganism which is selected from microorganisms belonging to Escherichia coli, Bacillus subtilis, or Saccharomyces cerevisiae. The GPO is useful for the quantitative analysis of triglyceride, glycerine, etc., and the determination of lipase activity, when used in combination with other enzymes such as lipase, glycerol kinase, or the like, or with an ATP reagent.
