Protease - Wikipedia
A protease (also called a peptidase, proteinase, or proteolytic enzyme) [1] is an enzyme that catalyzes proteolysis, breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products. [2] .
Proteases: History, discovery, and roles in health and disease
Proteinases are the largest enzyme gene family in vertebrates. There are 641 protease genes in the human and 677 in the mouse ( i.e. ∼3% of the human and mouse genome). Proteolysis occurs in virtually all stages of a cell's life, in all cell compartments, and in many stages of a protein's existence: from processing of preproproteins ...

Proteases are ubiquitous in biosystems where they have diverse roles in the biochemical, physiological, and regulatory aspects of cells and organisms. Proteases represent the largest segment of the industrial enzyme market where they are used in detergents, in food processing, in leather and fabric upgrading, as catalysts in organic synthesis ...

Protease - an overview | ScienceDirect Topics
Protease is an enzyme that catalyzes the hydrolysis of peptide bonds within proteins. Nearly 2% of the proteins encoded by the human genome are proteases, making up one of the largest classes of enzymes [1].
Proteinase - an overview | ScienceDirect Topics
The proteinases (endopeptidases) are proteolytic enzymes that are active in homeostatic remodeling of the ECM during health and in its degradation during inflammation. 53 These enzymes occur both intracellularly and extracellularly in tissue fluids and plasma and have been classified into four categories based on functional catalytic groups 54 ...
Protease mechanisms | Learn Science at Scitable - Nature
Enzymes that catalyse the hydrolytic cleavage of peptide bonds are called proteases. Proteases fall into four main mechanistic classes: serine, cysteine, aspartyl and metalloproteases.
Protease propeptide structures, mechanisms of activation, and …
Proteases are a diverse group of hydrolytic enzymes, ranging from single-domain catalytic molecules to sophisticated multi-functional macromolecules. Human proteases are divided into five mechanistic classes: aspartate, cysteine, metallo, serine and threonine proteases, based on the catalytic mechanism of hydrolysis.
Proteinase - an overview | ScienceDirect Topics
Proteinases catalyze the hydrolysis of peptide bonds in proteins. The selectivity of action of some proteinases is shown in Figure 1.

In particular, we are becoming aware of the subtle role that proteases play in signaling events within proteolysis networks, in which the enzymes act synergistically and form alliances in a web-like fashion. Proteases come in different flavors.
