Fused RolA protein enhances beta-glucoronidase activity 50-fold: implication for RolA mechanism of action.

abstract：BACKGROUND:Haloalkane dehalogenases (EC 3.8.1.5, HLDs) are α/β-hydrolases which catalyze the irreversible cleavage of carbon-halogen bonds of haloalkanes, producing an alcohol, a halide and a hydrogen ion. Haloalkanes are acutely toxic to animals and humans and their toxic effects are mainly observed in the liver, kidn...
