Pressure Cycling-Accelerated Digestion with Trypsin: Effect of Urea on Digestion at Pressure

Introduction
The positive effect of Pressure Cycling Technology (PCT) on digestion with trypsin is well established [1-5], and has been shown to result in improved sequence coverage, higher peptide intensities and significantly reduced digestion times. Additionally, the enhancing effect of PCT on the activity of several other enzymes, including Lys-C [6], chymotrypsin [7, 8], Glu-C [9], thermolysin [10], Proteinase K [11], PNGase F [12], and lysozyme [13], has been reported.

Pressure-Accelerated Native Protein Deglycosylation by PNGase F Enzyme

Introduction
The positive effect of Pressure Cycling Technology (PCT) on digestion with trypsin is well established [1-4], and has been shown to result in improved sequence coverage, higher peptide intensities and significantly reduced digestion times. Additionally, the enhancing effect of PCT on the activity of several other enzymes, including Lys-C, chymotrypsin, Glu-C, thermolysin, Proteinase K, and lysozyme, has been reported [5-11]. Pressure-accelerated deglycosylation by PNGase F of denatured glycoproteins has previously been shown [12].
