专利号:US-5801047-A 优先权日:1992-11-25 标题:Method for making stable extracellular tyrosinase and synthesis of polyphenolic polymers therefrom 发明人:DELLA-CIOPPA GUY RICHARD; GARGER JR STEPHEN JOHN; HOLTZ RICHARD BARRY; MCCULLOCH MICHAEL JAY; SVERLOW GENADIE GLEB 权利人:BIOSOURCE TECH INC 摘要:A process for the in vitro production of chemically modified polyphenolic polymer (PPP). First, stable, highly active extracellular tyrosinase is produced from genetically transformed microorganism such as Streptomyces antibioticus. The tyrosinase is then incubated with a reaction substrate such as 1-tyrosine, hydrolyzed protein, or an oligopeptide in combination with 1-tyrosine. The ratio of the oligopeptide/tyrosine combination as well as variation in the concentration of tyrosinase can be used to modify the color, the molecular size, and the spectral absorbance properties of the PPP produced. Alternatively, or additionally, oxidants such as hydrogen peroxide or hypochlorite can be used to modify the color of the PPP, regardless of the method used to produce the PPP, and the PPP can subsequently be fractionated using molecular weight cut-off ultrafiltration. Organic solvents can also be used in the method of making PPP to produce PPPs having variable but reproducible physical properties.
