WebThe identification and characterization of the four active neutrophil serine proteases (NSPs) have provided a better understanding of their roles in various physiological and pathological processes. The availability of appropriate tools such as WebProtease inhibitors are synthetic drugs that inhibit the action of HIV-1 protease, an enzyme that cleaves two precursor proteins into smaller fragments.These fragments are needed for viral growth, infectivity and replication. Protease inhibitors bind to the active site of the protease enzyme and prevent the maturation of the newly produced virions so …

http://guweb2.gonzaga.edu/faculty/cronk/CHEM440pub/serine-proteases.html Serine proteases are characterised by a distinctive structure, consisting of two beta-barrel domains that converge at the catalytic active site. These enzymes can be further categorised based on their substrate specificity as either trypsin-like, chymotrypsin-like or elastase-like. Trypsin-like Trypsin-like proteases cleave … See more 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. They are found ubiquitously in both See more The main player in the catalytic mechanism in the serine proteases is the catalytic triad. The triad is located in the active site of the enzyme, where catalysis occurs, and is … See more Mutations may lead to decreased or increased activity of enzymes. This may have different consequences, depending on the normal function of the serine protease. For … See more Due to their catalytic activity, some serine proteases possess potent antimicrobial properties. Several in vitro studies have demonstrated the efficacy of some proteases in … See more The MEROPS protease classification system counts 16 superfamilies (as of 2013) each containing many families. Each superfamily uses the catalytic triad or dyad in a different protein fold and so represent convergent evolution of the catalytic mechanism. … See more Host organisms must ensure that the activity of serine proteases is adequately regulated.
