SHC in vivo is a membrane-associated protein and can be solubilized from cell extracts by nonionic detergents, such as Triton X-100 or octylthioglucopyranoside. The enzyme is attached to the inner side of the cytoplasmic membrane by interactions of hydrophobic residues with the phospholipids. The membrane-binding part of the enzyme is a nonpolar region that is encircled by positive-charged amino acids enforcing the anchoring of the enzyme to the negatively charged surface of the phospholipid membrane
