Cysteine protease - Wikipedia
Cysteine proteases, also known as thiol proteases, are hydrolase enzymes that degrade proteins. These proteases share a common catalytic mechanism that involves a nucleophilic cysteine thiol in a catalytic triad or dyad.
Cysteine Protease - an overview | ScienceDirect Topics
Cysteine proteases play numerous indispensable roles in the biology of parasitic organisms. Aside from previously known general catabolic functions and protein processing, cysteine proteases may be key to parasite immunoevasion, excystment/encystment, exsheathing and cell and tissue invasion.

Cysteine proteases of parasites play key role in hemoglobin hydrolysis, blood cell invasion, egress, surface proteins processing (Lecaille et al., 2002; Sajid and McKerrow, 2002; Sijwali and Rosenthal, 2004). In 1937, papain was the first cysteine protease isolated and characterized from Carica papaya (Walsh, 2014). Papain and cathepsins belong ...
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.
The Role of Cysteine Proteinases and their Inhibitors in the Host ...
The serpins are essentially serine proteinase inhibitors [50,51], only some of them inhibit both serine and cysteine proteases . The mechanism by which cysteine proteases are inhibited involves the cleavage of the serpin, in some cases involving a stable covalent complex [52-54] and in other cases not . 3.
Cysteine Protease - an overview | ScienceDirect Topics
Cysteine proteases, also known as thiol-proteases, catalyse reactions through the cysteine group at their active sites (Mazorra-Manzano et al., 2013; Shah & Mir, 2019). Unlike aspartic proteases, cysteine and serine proteases employ amino acids as nucleophiles, while aspartic proteases use activated water molecules ( Bruno, Trejo, Aviles ...
Cysteine cathepsins: From structure, function and regulation …
2012年1月1日 · The view of cysteine cathepsins as lysosomal proteases is changing as there is now clear evidence of their localization in other cellular compartments. Besides being involved in protein turnover, they build an important part of the endosomal antigen presentation.
