Selective Synthesis of DOPA and DOPA Peptides by Native and Immobilized Tyrosinase in Organic Solvent

Authors


Abstract

3,4-Dihydroxyphenylalanine (DOPA)-containing peptides and proteins provide attractive design paradigms for pharmaceutical applications and engineering of synthetic polymers. An efficient and selective route to DOPA peptides by oxidation of L-tyrosine derivatives with tyrosinase is reported. The efficiency of the procedure was tested by using successively recycled tyrosinase immobilized on Eupergit®C250L and coated with polyelectrolytes by the layer-by-layer method.
