Inspired by the concept of bispecific antibodies, bispecific enzymes for the detoxification of organophosphates (OPs) were created by exploiting the homodimeric quarternary structure of bacterial phosphotriesterases (PTEs). Subunits of PTE variants from
Brevundimonas diminuta and
Agrobacterium radiobacter were successfully combined and their heterodimerization was stabilized by rational protein engineering. The resulting bioscavenger from PTEs with different bacterial origin exhibits an unprecedented broad OP substrate profile towards nerve agents and pesticides.
