A group of membrane proteins can be extracted from membranes only by using detergents
All the proteins in this group have a similar amino acid sequence at their C-terminus: -KKKKKXXC (where K stands for lysine, X stands for any amino acid, and C stands for cysteine). This sequence is essential for their attachment to the membrane. What is the most likely way in which the C-terminal sequence attaches these proteins to the membrane? (a) The cysteine residue is covalently attached to a membrane lipid. (b) The peptide spans the membrane as an ? helix. (c) The peptide spans the membrane as part of a ? sheet. (d) The positively charged lysine residues interact with an acidic integral membrane protein.
