Recombinant tyrosinase for controlled biopolymer crosslinking

Overview

The recombinant tyrosinase technology offers a novel approach to enzyme-mediated crosslinking of biological molecules, providing precise control over reaction kinetics. By leveraging recombinant methods, tyrosinase can be produced at a large scale and tailored to have broader substrate reactivity compared to its natural form. This innovation enables the crosslinking of proteins, polysaccharides, and other biopolymers through hydroxylation and oxidation under mild conditions such as moderate temperatures and normal pressures. The biodegradable nature of tyrosinase, along with its ability to be deactivated, adds to its practicality and safety in various applications.
