WebbThe proteolytic activity of MMGP1 was confirmed by tricine SDS-PAGE and gel filtration chromatography. Liquid chromatography-mass spectrometry analysis of MMGP1 treated bovine serum albumin (BSA), RNaseA and casein substrates revealed that the peptide does not have common cleavage position and it cleaves the substrates non-specifically at all … WebbBACKGROUND & AIMS:: Colon tissues of patients with inflammatory bowel disease (IBD) have been reported to have increased proteolytic activity, but no studies have clearly addressed the protease to anti-protease balance in the pathogenesis of colitis. We investigated the role of Elafin, a serine protease inhibitor expressed by skin and mucosal …
WebbAspartic proteases are of significant importance for medicine and biotechnology. In spite of sufficient evidence that many non-Saccharomyces yeasts produce extracellular proteases, previous research has focused on the enzymes of Candida species because of their role as virulence factors. Nowadays, there is also increasing interest for their … WebbProtease being an important industrial enzyme, it is necessary to have an efficient screening method to detect proteolytic activity containing bacteria to support the production of enzyme in large-scale. Even though, proteolytic activity can be readily observed, in certain cases, it is difficult to detect and retrieve the colonies.
WebbTo clarify soil protease assays and improve their accuracy, we describe a comprehensive protocol in which field-moist soil is incubated with casein for 2 h at 50°C, and protease activity is determined by colorimetric measurement of the tyrosine produced after correction for soil- and substrate-only controls. WebbProteolytic activities after the addition of the diagnostic inhibitors were calculated according to the Lee & Lin method. 14 Natural inhibitors of acid, neutral and alkaline proteases were determined according to Lee and Lin. 14 The detailed protocols are described by Łoś and Strachecka. 9 Pepsin was used as a marker for acidic, whereas …
