enzyme activityThe unit of measure for.1961 International Conference on Enzymologyregulations: 1 enzyme activity unit refers to the optimum condition (25 ℃)condition）Under, 1 μ can be converted within 1 minutemoleThe amount of enzyme in the substrate, or 1 micromol in the conversion substrateGroupThe amount of enzyme.
Enzyme activity unit: a unit used to express the activity of an enzyme, usually expressed in the amount of enzyme.
Definition of 1961 International Enzymology Conferenceenzyme activityInternational unit, which is specified as: under specific conditions, convert 1 μ m within 1 minutemoleThe substrate, or the amount of enzyme required for 1 micromol of related groups in the substrate, is called an international unit IU of enzyme activity.
In 1972, the international enzymology conference also stipulated an enzyme activity unit, Kat, as the amount of enzyme that can convert 1 mole of substrate in 1 second under the most appropriate conditions.Conversion relationship between Kat and IU: 1 Kat=6 × 10sevenIU, 1IU=about 16.67n Kat.
