Purification and properties of sterol carrier protein1.
Previous studies have demonstrated that both the 105,000 X g soluble supernatant (S105) and microsomal membranes from rat liver are required for the enzymatic conversion of squalene to cholesterol (Scallen, T.J., Dean, W.J., and Schuster, M.W. (1968) J. Biol. Chem. 243, 5202). It was postulated that S105 contained a noncatalytic carrier protein which was required for this enzymatic process (Sca...
متن کاملSterol carrier protein2. Delivery of cholesterol from adrenal lipid droplets to mitochondria for pregnenolone synthesis.
The ability of sterol carrier protein2 (SCP2) to mediate transfer of unesterified cholesterol from adrenal lipid inclusion droplets to mitochondria has been tested in an in vitro model system. Unlike mitochondrial utilization of cholesterol added in acetone or dimethyl sulfoxide, the unesterified cholesterol of lipid droplets did not provide a readily available source of substrate for mitochond...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولThe participation of sterol carrier protein2 in the conversion of cholesterol to cholesterol ester by rat liver microsomes.
The purification of sterol carrier protein2 (SCP2), purified 1500-fold to homogeneity from the 303,000 x g supernatant (S303) of rat liver, has recently been described (Noland, B. J., Arebalo, R. E., Hansbury, E., and Scallen T. J. (1980) J. Biol. Chem, 255, 4282-4289). Since SCP2 is required for the synthesis of cholesterol by microsomal membranes, it was decided to test the hypothesis that SC...
