entsyyminkääntökohdat
Ensymyyminkääntökohdat, also known as enzyme turnover numbers, represent a fundamental property of enzymes that quantifies their catalytic efficiency. It is defined as the maximum number of substrate molecules an enzyme molecule can convert into product molecules per unit of time when the enzyme is fully saturated with substrate. In simpler terms, it indicates how many times an enzyme can perform its catalytic function in a given period.
This value is a constant for a specific enzyme under defined conditions, such as temperature and pH.
The turnover number is determined experimentally by measuring the initial reaction rate at saturating substrate concentrations.
