On the Spatial Arrangement of Proteins in Microsomal Membranes from Rat Liver


Rat liver rough microsomes were labeled enzymatically with (125)I using lactoperoxidase and glucose oxidase. In intact microsomes only proteins exposed on the outside face of the microsomal membrane were iodinated. Low concentrations of detergent (0.049% deoxycholate) were used to allow entrance of the iodination system into the vesicles without… (More)
