1 Using scanning cysteine mutagenesis, followed by PEGylation, one can map the accessibility of the introduced cysteines, hence inferring the membrane topology of the protein.We used PEGylation to determine the membrane topology of the sterol regulatory domain of a cholesterol synthesis enzyme, squalene monooxygenase, identifying that it is anchored to the membrane via a re-entrant loop.
