Sterol chain
網頁2016年3月22日 · Sterols are an end-product of the cyclization of the C 30 isoprenoid 2,3-oxidosqualene. Cyclisation either produces lanosterol as in animals, fungi, and some algae and bacteria or cycloartenol as in higher plants and most algae (Fig. 2 ). 網頁2024年1月16日 · The Ω1-loops of the LAM SDs are too short to surround the acyl chain of the bound sterol, and therefore cannot close the tunnel entrance. Ergosterol binding induces a slight conformational change in the Lam2 SD2 around the tunnel entrance ( …
