Two putative parathion hydrolases of Bacillus halodurans, PTEa with 679 amino acid residues and PTEb with 331 amino acid residues, were found by using the protein sequence of parathion hydrolase from Flavobacterium to BLASTP the genomes of 4 Bacillus strains.

Sequence analysis and structure prediction of methyl parathion hydrolase OPHC2;

Study on reaction system and characteristics of methyl parathion hydrolase;

Methyl parathion hydrolase (MPH) was a novel member of phosphotriesterase.

Parathion-degrading enzyme from Aspergillus niger Y-8 cell of culture at 30℃, 5d was purified to SDS-PAGE homogenous by (NH4)2 SO4 precipitation, DEAE-cellulose chromatography, Sephadex G-100 gel filtration with 13.

Study on the mutation and rejuvenation of a parathion-degrading bacterium;

Carboxylesterase and organophosphorus hydrolase (OPH) are capable of hydrolyzing and detoxifying different pesticides.

In the present study,N-termini sequence(inpn) of ice-nucleating protein gene from Pseudomonas syringae,was employed as the anchoring motif to direct the cell-surface display of a heterologous organophosphorus hydrolase in P.

In the present study,the N-terminal domain of ice nucleation protein InaK from Pseudomonas syringae KCTC1832 strain was used as an anchoring motif,to display organophosphorus hydrolase(OPH) that was encoded by opd gene of Flavobacterim sp.
