Genetically engineered organophosphorus acid anhydrolases (OPAA) with improved catalytic efficiency and relaxed stereospecificity are provided. The variants typically include a mutation at the residue corresponding to H343 of wildtype Alteromonas sp. OPAA. The mutation allows the OPAA enzyme to effectively process both VR enantiomers. The OPAA optionally include one or more mutations selected the residues corresponding to Y212, V342, and I215 of wildtype Alteromonas sp. OPAA which improve the enzyme's catalytic efficiency for VX and VR. A particularly preferred OPAA includes mutations at the residues corresponding Y212F, V342L, I215Y, and H343D relative to wildtype Alteromonas sp. OPAA. Compositions including an effective amount of OPAA to increase hydrolysis of an organophosphate, and methods of use thereof for treating subjects exposed to an organophosphate, or a surface or liquid contaminated with an organophosphate are also provided.

11 POTENTIAL GRADIENT AMPLIFIED DETECTION OF CHEMICAL AGENTS US15880815 2018-01-26 US20180217085A1 2018-08-02 Paul V. BRAUN; Mohammad Amdad Ali
New approaches for selective detection of chemical agents such as sarin are necessary because of the high toxicity of sarin and related compounds, the potential of these compounds to be used as weapons of mass destruction, and the limitations of current detection methodologies. Herein is described an apparatus and a method for selective and amplified detection of sarin simulants deposited via an aerosol process. The simulant absorbs into a hydrogel, where it hydrolyzes upon contact with water producing elemental ions. The elemental ions are then concentrated via an ionic chemical potential gradient to a sensor, where it is detected. This technique has potential to amplify the capture efficiency of a sensor by a 1000-fold within couple of minutes.
