The organophosphate-degrading enzyme from Agrobacterium radiobacter displays mechanistic flexibility for catalysis

Ely, Fernanda; Hadler, Kieran S; Gahan, Lawrence; Guddat, Luke; Ollis, David; Schenk, Gerhard


The OP (organophosphate)-degrading enzyme from Agrobacterium radiobacter (OpdA) is a binuclear metallohydrolase able to degrade highly toxic OP pesticides and nerve agents into less or non-toxic compounds. In the present study, the effect of metal ion substitutions and site-directed mutations on the catalytic properties of OpdA are investigated. The study shows the importance of both the metal ion composition and a hydrogen-bond network that connects the metal ion centre with the...[Show more]
