Abstract excerpt
Molecular dynamics simulations were carried out to calculate the free energy change difference of two collagen-like peptide models for Gly --> Ser mutations causing two different osteogenesis imperfecta phenotypes. These simulations were performed to investigate the impact of local amino acid sequence environment adjacent to a mutation site on the stability of the collagen. The average free energy differences for...
