Under acidic conditionsEscherichia coliribonuclease HI* (RNase H*) adopts a partially folded state with all of the properties of a molten globule. Using amide hydrogen exchange carried out under acid state conditions, followed by quenching and NMR detection on the native state, we have determined the residues that are responsible for the observed structure of the acid state. Although RNase H* is a mixed α + β protein, a helical subdomain (helices A, D, and B) defines the structure of the acid state. This structure correlates with the rare higher energy conformations detected under native conditions and with data for the earliest intermediates populated in the kinetic folding pathway of the protein.
