Knowledge of the transition state is key to understanding a reaction mechanism. This vital information has been lacking for integral membrane protein folding, but now recent advances have given insight into the structure of their folding transition state. This progress has arisen through the successful translation of a classical protein engineering method, phi value analysis, from water-soluble proteins to the hydrophobic, membrane-embedded protein class. This review covers the transition state for the folding of alpha helical membrane proteins. Helix formation in the transition state correlates with sequence position and the order of transmembrane insertion into the cell membrane, showing that in vitro measurements, in entirely different conditions to natural membranes, may reflect the cellular situation.
