Among structural biology techniques, Nuclear Magnetic Resonance (NMR) provides a holistic view of structure that is close to protein structure in situ. Namely, NMR imaging allows for the solution state of the protein to be observed, derived from Nuclear Overhauser Effect restraints (NOEs). NOEs are a distance range in which hydrogen pairs are observed to stay within range of, and therefore experimental data which computational models can be compared against. To that end, we investigated the effects of adding the NOE restraints as distance restraints in Molecular Dynamics (MD) simulations on the 24 residue HP24stab derived villin headpiece subdomain to …

Though eradicated in most of the world, poliovirus remains a common model virus for a family of mammalian viruses known as Picornaviruses. Despite the development of a vaccination, little is understood about the infection process, particularly the mechanism of cell entry. Experimental studies have attempted to elucidate the dynamics of this process and have proposed pathways focused on VP4, the smallest of the four peptides which makes up the viral capsid, and its interaction with the pentameric interfaces of the five fold axes. This study utilizes coarse-grained molecular dynamics to supplement these proposed mechanisms with simplified simulations which reduce the …
