An exoenzyme, also known as an extracellular enzyme, is an enzyme that is secreted by a cell and functions outside of that cell. These enzymes are produced by various organisms, including bacteria, fungi, and some plants and animals. Unlike intracellular enzymes, which operate within the cell, exoenzymes are released into the extracellular environment to perform their catalytic roles.

The primary function of exoenzymes is to break down complex molecules in the environment into smaller, more manageable units that can then be absorbed and utilized by the organism. For example, many bacteria and fungi secrete exoenzymes like cellulases, proteases, and lipases to digest complex carbohydrates, proteins, and lipids in their surroundings. This process is crucial for nutrient acquisition, especially for organisms that cannot directly ingest large food particles.

Exoenzymes play vital roles in diverse ecological processes. In decomposition, they are essential for breaking down dead organic matter, recycling nutrients back into the ecosystem. In symbiotic relationships, such as the interaction between plants and mycorrhizal fungi, exoenzymes facilitate nutrient exchange. In pathogenic organisms, exoenzymes can contribute to tissue damage and disease progression by breaking down host tissues. The study of exoenzymes is important in fields ranging from industrial biotechnology, where they are used in processes like food production and detergent manufacturing, to medicine, where they are targets for antimicrobial therapies.
