Renaturation is the process of reforming the native structure of a protein or nucleic acid that has been denatured. This process can also be referred to as refolding, reconstitution, or reassembly. Refolding involves the recovery of the native conformation of a protein after it has been disrupted. Reconstitution is the process of assembling a functional complex from its isolated components. While reassembly is the process of restoring a structure that has been taken apart. These synonyms help describe the process of renaturation, which is an important process in molecular biology and biotechnology.
