CC -!- FUNCTION: Has an unusual substrate specificity for synthetic
CC organophosphate triesters and phosphorofluoridates. All of the
CC phosphate triesters found to be substrates are synthetic compounds. The
CC identity of any naturally occurring substrate for the enzyme is
CC unknown. Has no detectable activity with phosphate monoesters or
CC diesters and no activity as an esterase or protease. It catalyzes the
CC hydrolysis of the insecticide paraoxon at a rate approaching the
CC diffusion limit and thus appears to be optimally evolved for utilizing
CC this synthetic substrate (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=An aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl
CC alcohol.; EC=3.1.8.1;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00679};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000255|PROSITE-
CC ProRule:PRU00679};
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Peripheral membrane
CC protein {ECO:0000250}.
CC -!- PTM: Predicted to be exported by the Tat system. The position of the
CC signal peptide cleavage has been experimentally proven.
CC -!- SIMILARITY: Belongs to the metallo-dependent hydrolases superfamily.
CC Phosphotriesterase family. {ECO:0000255|PROSITE-ProRule:PRU00679}.
