‘Processivity’ describes how well an enzyme can consecutively catalyse many reactions while still remaining attached to the desired substrate. An enzyme that can be classed as having a high processivity will remain bound to a polymer while catalysing many reactions in an elongation or digestion process [1].
An enzyme that instead releases its substrate after every step is known as a distributive enzyme.
