Pressure-Enhanced Enzymes Application Notes Display: ASC DESC Sort By Title Date Ordering Pressure Cycling-Accelerated Digestion with Trypsin: Protein Modifications and Enzyme Specificity Introduction Here we report that 90 minute pressure-accelerated trypsin digestion of whole tissue lysate is comparable to, or better than, standard overnight digestion. The goal of this work is to provide the user with the best set of starting conditions for pressure-enhanced trypsin digestion of complex samples. Download View Details III. Effect of High Pressure and Temperature on Papainase Digestion Rate INTRODUCTION High hydrostatic pressure (HPP) has been used for decades in the food industry for the inactivation of microbes and of the oxidases responsible for the browning of fruits and vegetables [5]. In biotechnology, HHP has been shown to accelerate the activity of proteases used for the digestion of proteins prior to mass spectrometry. While the positive effects of temperature and pressure on the activity of several proteases are known [6,7], the potential synergy of elevated temperature with pressure has not been fully characterized, particularly in terms of real-time kinetic studies. Using a high pressure optical cell coupled to a programmable high pressure generator, the effects of elevated pressure (0-60,000 psi) and temperature (22°C to 60°C) on the rate at which papainase digests a synthetic substrate was investigated.
