Abstract: All the forms of 3C protease previously found were isolated and purified. A 3D poly-merase's fragment covalently bound with 3C protein does not affect the specific proteolytic activity of the enzyme, whereas the elimination of 26 N-terminal amino acid residues of 3C protease leads to its inactivation.
