Before revision:  The proposed quantum protein folding theory affords a unifying approach to the study of a large class problems of biological conformational change , for example, the quantum transition of tubulin dimer in microtubules, the ligand binding in G protein coupled receptors in membrane, the histone modification in nucleic acid through atomic group binding and the protein photo folding processes, etc. In all these applications the concise rate formula is suggested as a useful tool for investigators .
