Serine proteases (or serine endopeptidases) are enzymes that cleave peptide bonds in proteins. Serine serves as the nucleophilic amino acid at the (enzyme's) active site . [ 1 ] They are found ubiquitously in both eukaryotes and prokaryotes .
IgA protease (EC 3.4.21.72, IgA-specific serine endopeptidase, IgA proteinase, IgA-specific proteinase, immunoglobulin A protease, immunoglobulin A proteinase) is an enzyme. [1] [2] This enzyme catalyses the following chemical reaction [reaction equation needed]
Glutamyl endopeptidase (EC 3.4.21.19, SspA, V8 protease, GluV8, endoproteinase Glu-C, staphylococcal serine proteinase) is an extracellular bacterial serine protease of the glutamyl endopeptidase I family that was initially isolated from the Staphylococcus aureus strain V8.
Pancreatic elastase 1 is a serine endopeptidase, a specific type of protease that has the amino acid serine at its active site. Although the recommended name is pancreatic elastase, it can also be referred to as elastase-1, pancreatopeptidase, PE, or serine elastase.
Endopeptidase or endoproteinase are proteolytic peptidases that break peptide bonds of nonterminal amino acids (i.e. within the molecule), in contrast to ...
Prolyl endopeptidase is a large cytosolic enzyme that belongs to a distinct class of serine peptidases. It was first described in the cytosol of rabbit brain as an oligopeptidase, which degrades the nonapeptide bradykinin at the Pro-Phe bond. [6]
Glutamyl endopeptidase I is a family of extracellular bacterial serine proteases. The proteases within this family have been identified in species of Staphylococcus, Bacillus, and Streptomyces, among others. The two former are more closely related, while the Streptomyces-type is treated as a separate family, glutamyl endopeptidase II. [1]
Enzyme ClpP is a highly conserved serine protease present throughout bacteria and also found in the mitochondria and chloroplasts of eukaryotic cells. [7] [8] The ClpP monomer is folded into three subdomains: the "handle", the globular "head", and the N-terminal region. By itself, ClpP can assemble into a tetradecamer complex (14-members) and ...
