Proteolytic enzyme, any of a group of enzymes that break long chainlike molecules of proteins into peptides and eventually into amino acids. There are two major groups of proteolytic enzymes, exopeptidases and endopeptidases.

Proteolysis is the breakdown of proteins into smaller polypeptides or amino acids. Uncatalysed, the hydrolysis of peptide bonds is extremely slow, taking hundreds of years. Proteolysis is typically catalysed by cellular enzymes called proteases, but may also occur by intra-molecular digestion.
6 sie 2017 · Proteolysis Definition. Proteolysis is the hydrolysis of the peptide bonds that hold proteins together, resulting in the breakdown of proteins into their key components, peptides and amino acids.
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]
11 maj 2023 · Proteolysis is the process of breaking proteins into peptides and amino acids in living organisms. It is a prolonged process catalyzed by specific enzymes called proteases, which are present in bacteria and plants but most abundant in animals. Without these enzymes, the cleavage of protein bonds may take hundreds of years.
Proteolytic Enzyme. Any enzyme that catalyzes the splitting of proteins into smaller peptide fractions and amino acids by a process known as proteolysis.
Now we know that the mouse and human genomes encode ∼200 metalloproteinases, the largest group in the proteolytic enzyme realm . Most of these enzymes are secreted from cells or plasma membrane–bound, and they act pericellularly and extracellularly.
