摘要:
57 The determination of a substrate or an activity of an enzyme in a sample containing ammonia by using a reaction system which forms ammonia can be performed by decomposing ammonia in the sample with an ammonia-decomposing reagent system, adding a reagent system necessary for the formation of ammonia from the substrate or the substrate for the enzyme to form ammonia and determining the formed ammonia.
摘要:
Triglycerides in a sample are quantitatively determined using a test composition having a system for converting the triglycerides to fatty acids and glycerol, a system for oxidizing the glycerol, and a system for determining the amount of oxygen consumed or the amount of hydrogen peroxide or glyceraldehyde formed in the oxidation of the glycerol.
摘要:
A novel cholesterol oxidase having a high substrate affinity for cholesterol, and a wide working pH range is provided, as well as a method for the production of said cholesterol oxidase which comprises culturing a microorganism belonging to the genus Escherichia which carries a recombinant DNA comprising a DNA derived from Brevibacterium sterolicum and defined in the Sequence Listing by SEQ ID NO: 1.

摘要:
A novel cholesterol oxidase is disclosed having a high substrate affinity, high activity and operable over a wide pH range, including acid value. The enzyme is produced in low yield by microorganisms of the species Brevibacterium sterolicum . Improved yields are obtained by transforming microorganisms of the species E.coli with the DNA from Brevibacterium sterolicum and which encodes the novel enzyme.
摘要:
Neuraminidase is produced by culturing a neuraminidase producing microorganism belonging to the genus Micromonospora. The neuraminidase is useful for the quantitative determination of a sialic acid-containing substance in a sample.
摘要:
A novel acetylpolyamine amidohydrolase is described. The enzyme specifically hydrolyzes the amino bond in acetylputrescine, acetylcadaverine, acetylspermidine and acetylspermine with strong substrate affinity. The enzyme is preferably produced by culturing a microorganism belonging to the genus Mycoplana, and is used in the quantitative determination of polyamine contained in a living body sample, which is useful for cancer diagnosis.
