1 Acid catalysis of the formation of the slow-folding species of RNase A: evidence that the reaction is proline isomerization. Proline ribonuclease A family member 1, pancreatic Homo sapiens
2 Earlier data, showing that the kinetic properties of the U(1) right arrow over left arrow U(2) reaction in refolding conditions differ from those of proline isomerization, can be explained if there is kinetic coupling between early steps in the folding of U(1) and its conversion to U(2).The existence of two acid-catalyzed reactions that are distinguished by the HClO(4) concentration at which catalysis begins suggests that at least two essential proline residues produce slow-folding species of RNase A by isomerization after unfolding. Proline ribonuclease A family member 1, pancreatic Homo sapiens
