Molecular cloning, purification and biochemical characterization of a novel pyrethroid-hydrolyzing carboxylesterase gene from Ochrobactrum anthropi YZ-1

► Strain YZ-1 capable of degrading pyrethroids was isolated and identified. ► The genomic library of strain YZ-1 was constructed successfully. ► The cloned pytZ was a new pyrethroid-degrading gene. ► PytZ displayed broad substrate specificity, high enzyme activity and stability. ► It provided a favorable choice for the biodegradation of pyrethroids residues.
