Revolution Number

The turnover number is an indicator of enzyme activity, which characterizes the number of substrate molecules that are affected by one enzyme molecule per unit of time (usually 1 minute).

In other words, the turnover number shows how many molecules of substrate can be converted into a product by one molecule of enzyme per minute. The higher the number of revolutions, the higher the activity of the enzyme.

The turnover number depends on the nature of the enzyme and the reaction conditions. For most enzymes, the speed ranges from 10 to 1000 per minute. However, there are enzymes with very high activity, in which the number of revolutions can reach several million per minute.

Thus, the turnover number is a key indicator of the catalytic activity of enzymes, allowing us to quantify their ability to accelerate biochemical reactions in living organisms.
