Amino groups, sulfhydryl groups or oxidation-induced aldehydes on erythrocyte membrane proteins and/or glycoproteins, were reacted with biotinyl N-hydroxysuccinimide ester (BNHS), 3-(N-maleimido-propionyl) biocytin (MPB) or biocytin hydrazide (BCHZ), respectively. The detergent-lysed biotinylated samples were subjected to SDS-polyacrylamide gel electrophoresis, and the

Membrane proteins play key roles in cellular functions, their activity mainly depending on their topological arrangement in membranes. Structural studies of membrane proteins have long adopted a protein-centric view regarding the determinants of membrane protein topology and function. Several studies
