metabolism | enzyme undergoes cholesterol-dependent proteasomal degradation when cholesterol is in excess. The amphipathic helix within the first 100 amino acids of squalene monooxygenase attaches reversibly to the ER membrane depending on cholesterol levels. With excess, the helix is ejected and unravels, exposing a hydrophobic patch, which then serves as a degradation signal | Homo sapiens |
