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] They do this by cleaving the peptide bonds within proteins by hydrolysis, a reaction where water ...
Proteases: Multifunctional Enzymes in Life and Disease - PMC
Proteases are the efficient executioners of a common chemical reaction: the hydrolysis of peptide bonds (16). Most proteolytic enzymes cleave α-peptide bonds between naturally occurring amino acids, but there are some proteases that perform slightly different reactions.

蛋白酶 （protease，proteinase）又称 肽酶 （peptidase）、 蛋白水解酶 （proteolytic enzyme）或 蛋白質分解酶[1]，是 生物體 內一類催化 蛋白質 或 肽类 中 肽键 水解 的 酶 （酵素），可將蛋白質分解成較小的 多肽 或單一 氨基酸，並促進新蛋白質產物的形成 [2]。 尽管 国际生物化学和分子生物学联盟命名委员会 认为蛋白酶与肽酶为同义词 [3]，仍有些学者定义两者不同，例如：蛋白酶是 内肽酶 [4]，或是认为“蛋白酶”为能够水解蛋白质分子内部的肽键，而“肽酶” …
Microbial proteases and their applications - PMC
Proteases (proteinases or peptidases) are a class of hydrolases that cleave peptide chains in proteins. Endopeptidases are a type of protease that hydrolyze the internal peptide bonds of proteins, forming shorter peptides; exopeptidases hydrolyze the terminal peptide bonds from the C-terminal or N-terminal, forming free amino acids.

Proteases: History, discovery, and roles in health and disease
Some examples of the major classes of proteolytic enzymes (aspartic, serine, cysteine, metallo) that were well studied before 1970 are as follows. Pepsin, an aspartic protease of the stomach, was one of the first enzymes to be discovered, characterized, and named (in 1825), and it was crystallized in 1930 .
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].
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 Enzymes: Highlights on Potential of Proteases as
2021年2月2日 · Protease enzymes are required for the hydrolysis of large polypeptides into smaller peptides and amino acids, thus facilitating their absorption by the cell. The protease enzymes such as those secreted by pancreas, intestine provide the essential amino acids as nutrition and helps in body keeping and mass balance.
