Substrate specificity of Tulane virus protease.
Tulane virus (TV) is a cultivable calicivirus isolated from rhesus monkeys. In this study, we characterized the substrate specificity of TV protease in trans using recombinant proteases and TV polyprotein fragments containing the predicted proteolytic cleavage sites. Cleavage products have been obtained from 4 of the 5 fragments containing (573)Q-S(574) between the helicase and 3A-like protein,...
متن کاملSubstrate specificity of the Escherichia coli outer membrane protease OmpP.
Escherichia coli OmpP is an F episome-encoded outer membrane protease that exhibits 71% amino acid sequence identity with OmpT. These two enzymes cleave substrate polypeptides primarily between pairs of basic amino acids. We found that, like OmpT, purified OmpP is active only in the presence of lipopolysaccharide. With optimal peptide substrates, OmpP exhibits high catalytic efficiency (k(cat)/...
متن کاملEvaluation of P1' substrate specificity of staphylococcal SplB protease.
Staphylococcus aureus is a dangerous human pathogen characterized by growing antibiotic resistance. Virulence of S. aureus relies on a variety of secreted and cell surface associated virulence factors among which certain proteolytic enzymes play an important role. Amid staphylococcal extracellular proteases, those encoded by the spl operon remain poorly characterized, both in terms of enzymolog...
متن کاملIn vitro reconstitution and substrate specificity of a lantibiotic protease.
Lacticin 481 is a lanthionine-containing bacteriocin (lantibiotic) produced by Lactococcus lactis subsp. lactis. The final steps of lacticin 481 biosynthesis are proteolytic removal of an N-terminal leader sequence from the prepeptide LctA and export of the mature lantibiotic. Both proteolysis and secretion are performed by the dedicated ATP-binding cassette (ABC) transporter LctT. LctT belongs...
متن کاملStructural determinants of tobacco vein mottling virus protease substrate specificity.
Tobacco vein mottling virus (TVMV) is a member of the Potyviridae, one of the largest families of plant viruses. The TVMV genome is translated into a single large polyprotein that is subsequently processed by three virally encoded proteases. Seven of the nine cleavage events are carried out by the NIa protease. Its homolog from the tobacco etch virus (TEV) is a widely used reagent for the remov...
