o Abstract
Protein prenyltransferases recognise an exposed Cys residue preceding the C-terminus of certain protein substrates. The enzymes covalently attach a prenyl group (farnesyl or geranyl-gernayl) to the Cys residue with the consequence that the (souble) protein is attached to the membrane. Examples of CAAX box proteins include the Ras-like proteins and the G-protein gamma and (some alpha) subunits.
