Intensification of Organophosphorus Hydrolase Synthesis by Using Substances with Gas-Transport Function

Applied Sciences, 2017
We have performed studies and comparative analysis of the biosynthesis characteristics of intracellular recombinant enzyme, such as hexahistidine-containing organophosphorus hydrolase (His6-OPH) in Escherichia coli SG13009[pREP4] cells when various ...

Organophosphorus pesticide tolerance of transgenic Arabidopsis thaliana by bacterial ophB gene encode organophosphorus hydrolase

Journal of Environmental Science and Health, Part B, 2021
Organophosphate hydrolase (OphB) gene from Pseudomonas sp. was transferred into Arabidopsis plants to observe the bioremediation ability and tolerance level of the transgenic plant to organophosphate pesticides contaminants. Gene transfer was observed by PCR of the transgenic Arabidopsis plants' genomic DNA.

Role of the Calcium Plateau in the Neuronal Injury and Behavioral Morbidities Following Organophosphate Intoxication [PDF]

, 2016
Organophosphate (OP) chemicals include nerve agents and pesticides, and there is a growing concern of OP based chemical attacks against civilians. Current antidotes are essential in limiting immediate mortality associated with OP exposure.

Towards a Capacitive Enzyme Sensor for Direct Determination of Organophosphorus Pesticides: Fundamental Studies and Aspects of Development

Sensors, 2003
The realisation of a miniaturised potentiometric enzyme biosensor is presented. The biosensor chip utilises the enzyme organophosphorus hydrolase (OPH) for the direct determination of pesticides. The transducer structure of the sensors chip consists of a

Altering the substrate specificity of organophosphorus hydrolase for enhanced hydrolysis of chlorpyrifos. [PDF]

Appl Environ Microbiol, 2004
ABSTRACTChlorpyrifos is one of the most popular pesticides used for agriculture crop protection, and widespread contamination is a potential concern. However, chlorpyrifos is hydrolyzed almost 1,000-fold slower than the preferred substrate, paraoxon, by organophosphorus hydrolase (OPH), an enzyme that can degrade a broad range of organophosphate ...

In vivo immobilization of an organophosphorus hydrolyzing enzyme on bacterial polyhydroxyalkanoate nano-granules

Microbial Cell Factories, 2019
Background Polyhydroxyalkanoate (PHA) are nano-granules naturally produced by bacteria. Two types of proteins, PHA synthase (PhaC) and phasins (PhaPs), are attached to the PHA surface by covalent and hydrophobic interactions.

Development of a biosensor for urea assay based on amidase inhibition, using an ion-selective electrode [PDF]

, 2011
A biosensor for urea has been developed based on the observation that urea is a powerful active-site inhibitor of amidase, which catalyzes the hydrolysis of amides such as acetamide to produce ammonia and the corresponding organic acid. Cell-free extract
