Analysis of catalytic properties of tripeptidyl peptidase I (TTP-I), a serine carboxyl lysosomal protease, and its detection in tissue extracts using selective FRET peptide substrate
(Elsevier Science Inc, 2016)
Tripeptidyl peptidase I (TPP-I), also named ceroid lipofuscinosis 2 protease (CLN2p), is a serine carboxyl lysosomal protease involved in neurodegenerative diseases, and has both tripeptidyl amino- and endopeptidase ...
Characterization, subsite mapping and N-terminal sequence of miliin, a serine-protease isolated from the latex of Euphorbia milii
(Elsevier B.V., 2013-04-01)
Miliin is a serine protease purified from the latex of Euphorbia milii. This work reports the effect of pH and temperature on the catalytic activity of miliin, using fluorescence resonance energy transfer (FRET) substrates. ...
Determination of Specificity and Biochemical Characteristics of Neutral Protease Isolated from Myceliophthora thermophila
(Bentham Science Publ Ltd, 2015-01-01)
Proteases hydrolyze polypeptides to release peptides and/or amino acids. This subclass of enzymes is among those with the most sales worldwide, particularly those produced by microorganisms. Proteases may be applied in the ...
Discriminating between the activities of human cathepsin G and chymase using fluorogenic substrates
(Wiley-Blackwell, 2011-08-01)
Cathepsin G (CG) (EC 3.4.21.20) and chymase (EC 3.4.21.39) are two closely-related chymotrypsin-like proteases that are released from cytoplasmic granules of activated mast cells and/or neutrophils. We investigated the ...
The use of Fluorescence Resonance Energy Transfer (FRET) peptidesfor measurement of clinically important proteolytic enzymes
(Academia Brasileira de Ciências, 2009-09-01)
Proteolytic enzymes have a fundamental role in many biological processes and are associated with multiple pathological conditions. Therefore, targeting these enzymes may be important for a better understanding of their ...
Neprilysin carboxydipeptidase specificity studies and improvement in its detection with fluorescence energy transfer peptides
(Walter de Gruyter & Co, 2007-04-01)
We examined the substrate specificity of the carboxydipeptidase activity of neprilysin (NEP) using fluorescence resonance energy transfer (FRET) peptides containing ortho-aminobenzoyl (Abz) and 2,4-dinitrophenyl (Dnp) as ...
P-I class metalloproteinase from Bothrops moojeni venom is a post-proline cleaving peptidase with kininogenase activity: Insights into substrate selectivity and kinetic behavior
(Elsevier B.V., 2014-03-01)
Snake venom metalloproteinases (SVMPs) belonging to P-I class are able to hydrolyze extracellular matrix proteins and coagulation factors triggering local and systemic reactions by multiple molecular mechanisms that are ...
The Autodepalmitoylating activity of APT maintains the spatial organization of Palmitoylated membrane proteins
(Cell Press, 2014-01)
The localization and signaling of S-palmitoylated peripheral membrane proteins is sustained by an acylation cycle in which acyl protein thioesterases (APTs) depalmitoylate mislocalized palmitoylated proteins on endomembranes. ...
