Sulfolobal Phosphotriesterase-Like (PLL) lactonases activity having enhanced properties and the uses thereof

摘要

The present invention provides mutated hyperthermophilic PTE having a lactonase activity derived from a hyperthermophilic phosphotriesterase corresponding to the consensus sequence of SEQ ID NO: 1, said mutated PTE comprising the at least one mutation choosen amongst 53 putative positions and said mutated PTE having enhanced properties. Also provided are compositions comprising the mutated hyperthermophilic PTE and the uses thereof, notably as bioscavenger of organophosphate compounds or as quorum quencher of the bacteria using lactones to communicate.
