Take a theoretical protein of 200 residues for example: there should be 240 N-H HSQC correlations (considering ASN, GLN, and et al) on NMR spectrum. However, due to the efficiency/efficacy of 15N...

Hello all, I am running NMR for an aqueous peptide sample in 90% H2O/ 10% D2O. The 1D 1H spectrum collected from a WATERGATE 3-9-19 sequence looked great, with the intensity of peptide peaks being...

I understand that the change of PMF can be calculated via Jarzynski equality if I have a number of replicate steered MD runs for that process. For example, I can pull an inhibitor from its binding...

Jarzynski's Equality relates work done during a process (e.g. steered molecular dynamics) to the Helmholtz free energy. I wonder if this requires my MD simulation to be NVT (not NPT)? If I use...
