Molecular Dynamics Studies Of Nucleic Acids And Ribonucleoprotein Complexes, Tyler James Mulligan

Master's Theses and Capstones

Molecular simulations of protein-nucleic acid complexes, as well as the HIV-1 Trans Activation Response Element (TAR) RNA molecule, were conducted. First, three different molecular dynamics techniques were studied on the molecule HIV-1 TAR RNA. The three techniques studied were classical molecular dynamics, steered molecular dynamics (SMD), and metadynamics. The classic molecular dynamics simulations were used to equilibrate the HIV-1 TAR RNA system, as well as every other system studied in this thesis. The SMD technique was used in order to observe the breaking force of the nucleotide interactions within TAR. This breaking force averaged to about 100pN. The metadynamics technique …
