Protein modification to provide enzyme activity

摘要

A naturally occurring protein is chemically modified to provide the protein with activity of a selected enzyme. The protein does not contain activity of the selected enzyme before modification. Modification is carried out by partially denaturing the protein, contacting the partially denatured protein with an enzyme inhibitor of the selected enzyme, crosslinking the protein in the presence of the inhibitor and recovering a modified protein having activity of the selected enzyme.
