D374Y | mutant kinetic data show a slower k-off for substrate domain EGF-A and full-length low density lipoprotein receptor unbinding which stems from the destabilizing effects of this mutation on PCSK9 hydration sites, with a concomitant increase in the persistence of the bound complex | Homo sapiens |

additional information | analysis of binding kinetics data for PCSK9 with full-length low density lipoprotein receptor ectodomain, and isolated EGF-A repeat of low density lipoprotein receptor. The fast k-on and entropically driven thermodynamics observed for PCSK9-EGF-A binding stem from the functional replacement of water occupying stable PCSK9 hydration sites. The relatively fast k-off observed for EGF-A unbinding stems from the limited displacement of solvent occupying unstable hydration sites. Conversely, the slower k-off observed for EGF-A and low density lipoprotein receptor unbinding from mutant D374Y stems from the destabilizing effects of this mutation on PCSK9 hydration sites, with a concomitant increase in the persistence of the bound complex | Homo sapiens |
