Proteomics beyond trypsin [PDF]
Peptide‐centered shotgun analysis of proteins has been the core technology in mass spectrometry based proteomics and has enabled numerous biological discoveries, such as the large‐scale charting of protein–protein interaction networks, the quantitative analysis of protein post‐translational modifications and even the first drafts of the human proteome.

Kinetic distance and kinetic maps from molecular dynamics simulation [PDF]
Characterizing macromolecular kinetics from molecular dynamics (MD) simulations requires a distance metric that can distinguish slowly-interconverting states. Here we build upon diffusion map theory and define a kinetic distance for irreducible Markov processes that quantifies how slowly molecular conformations interconvert.

Ultrasensitive surface-enhanced Raman scattering detection of trypsin based on anti-aggregation of 4-mercaptopyridine-functionalized silver nanoparticles: an optical sensing platform toward proteases [PDF]
In this work, a simple and sensitive surface-enhanced Raman scattering (SERS) strategy was developed for recognition and detection of trypsin, by using anti-aggregation of 4-mercaptopyridine (4-MPY)-functionalized silver nanoparticles (AgNPs) based on ...

Identification of trypsin-degrading commensals in the large intestine
Increased levels of proteases, such as trypsin, in the distal intestine have been implicated in intestinal pathological conditions 1 – 3 . However, the players and mechanisms that underlie protease regulation in the intestinal lumen have remained unclear.

Optimization of Enzymatic Hydrolysis and Decolorization Process of Walnut Protein
This paper aimed at the high-value utilization of walnut cake, a by-product of oil processing industry. The walnut protein (WP) was extracted by alkali extraction-acid precipitation method from cold-pressed walnut cake, then trypsin hydrolysis process ...

Water regulates the residence time of Benzamidine in Trypsin [PDF]
The process of ligand-protein unbinding is crucial in biophysics. Water is an essential part of any biological system and yet, many aspects of its role remain elusive. Here, we simulate with state-of-the-art enhanced sampling techniques the binding of Benzamidine to Trypsin which is a much studied and paradigmatic ligand-protein system.

The Effect of TiO2-Nanoparticle on the Activity and Stability of Trypsin in Aqueous Medium [PDF]
Trypsin (E.C.3.4.21.4) is a serine protease commonly used in proteomics for digestion of proteins. In the present study, the effect of nano-TiO2 on the conformation and catalytic activity of trypsin were studied.

Path separation of dissipation-corrected targeted molecular dynamics simulations of protein-ligand unbinding [PDF]
Protein-ligand (un)binding simulations are a recent focus of biased molecular dynamics simulations. Such binding and unbinding can occur via different pathways in and out of a binding site. We here present a theoretical framework how to compute kinetics along separate paths and to combine the path-specific rates into global binding and unbinding rates ...

Proteomics Using Protease Alternatives to Trypsin Benefits from Sequential Digestion with Trypsin
Trypsin is the most used enzyme in proteomics. Nevertheless, proteases with complementary cleavage specificity have been applied in special circumstances.
