Abstract
An enzyme sensor comprising an enzyme acting specifically on a substrate and a transducer for converting the quantitative change of a substance or heat which is produced or consumed during an enzyme reaction to an electrical signal, wherein the enzyme is glucokinase is disclosed. By the enzyme sensor of the present invention, an accurate determination of an amount of glucose in a sample is possible as well as an accurate determination of adenosine-5'-triphosphate (ATP). A response time of the sensor is almost constant after a long-term use and a decrease of the detecting ratio is very small.
