Renatured (Comment) | Organism |
---|---|
acid-denatured enzyme is able to regain the intact structure by neutralization, irreversible denaturation after exposure to an alkaline pH , denaturation under high pressure, reduced enzyme in 8 M urea or 6 M guanidine hydrochloride is completely denatured to a randomly coiled state, Ca2+ has a profound effect on the renaturation process | Aspergillus oryzae |
denaturation under high pressure, enzyme denatured by 8 M urea can refold to regain its activity. Rate and extent of reactivation increases in the presence of various other proteins, bovine serum albumin is most effective | Bacillus subtilis |
