Webb23 juli 2024 · To generate a prefusion-stabilized SARS-CoV-2 spike protein that expresses at higher levels and is more stable than our original S-2P construct ( 18 ), we analyzed the SARS-CoV-2 S-2P cryo-EM structure (PDB ID 6VSB) and designed substitutions based on knowledge of class I viral fusion protein function and general protein stability principles. Webbstability characteristics, thereby decreasing the protein’s suitability and effective use as a therapeutic (10, 11). Various modified synthetic analogs of human amylin have been made in an attempt to increase the solubility and stability of the resulting peptides. For example, pramlintide acetate is a synthetic analog of human-amylin–
WebbThe relative stability of the folded versus the denatured depends on the environment of the protein. Environmental conditions such as high temperature, extremes of pH, or the presence of organic solvents, can cause the unfolded state to become lower in energy than the folded state.
