  • Process for the production of modified proteins and product thereof
    Patent number: 4609625
    Abstract: A process is disclosed for chemically modifying naturally occurring proteins to produce enzyme-like modified proteins. The process comprises partially denaturing a cofactor containing holoprotein by removal of the cofactor to produce a partially denatured cofactorless or so-called apoprotein. The partially denatured protein is contacted with an inhibitor of a selected model enzyme and cross-linked. The resultant protein product is an enzyme-like modified protein having the catalytic characteristics of the model enzyme whose inhibitor is contacted with the partially denatured apoprotein.
