Inhibitors Comment Organism Structure
Urea the reversible unfolding/refolding process of the PLpro in the presence of urea is investigated. The zinc-binding domain of the enzyme starts to unfold at urea concentration below 0.35 M and reaches a first plateau at 1-3.5 M. At this stage, the palm and thumb core domains remain well folded but totally inactive Alphacoronavirus
