Abstract

D1 protease has been isolated from the alga (Scenedesmjus obliquus), wheat, and Synechocystis PCC 6803 and the genes encoding these enzymes have been cloned and sequenced. Native or recombinantly produced enzyme has been used to develop assays to detect herbicidal compositions capable of inhibiting the D1 protease enzyme.
