Chemical interaction between the immobilized enzymes on Cu‐MCM41 determinated by EPR

Badges of Immobilized Enzymes: Detection of Chemical Warfare Agents

Rapid detection of chemical warfare agents (CWAs) in all of its forms including gas and liquid is of paramount importance to protect the warfighter or first responders in homeland defense. CWAs such as OPs and vesicants pose serious threats because these agents can be ingested with contaminated food or rapidly penetrate skin. We reported that polyurethane immobilized cholinesterases (acetyl and...

The Investigation on Interaction between Two Hepatic Enzymes and some Minerals in Broiler Chickens

The objectives of this study were to determinethe interactions between two hepatic enzymes and some minerals in the liver of broiler chickens. The study was performed with male and female from 1 to 56 days of age of broiler chickens. Malic acid was added to the water and offered to chickens freely from the start to the end of the experiment with constant concentration. The treatments consisted ...

Fluorescence studies on the interaction between pyridoxal phosphate enzymes.

Rapid-scan EPR of immobilized nitroxides.

X-band electron paramagnetic resonance spectra of immobilized nitroxides were obtained by rapid scan at 293 K. Scan widths were 155 G with 13.4 kHz scan frequency for (14)N-perdeuterated tempone and for T4 lysozyme doubly spin labeled with an iodoacetamide spirocyclohexyl nitroxide and 100 G with 20.9 kHz scan frequency for (15)N-perdeuterated tempone. These wide scans were made possible by mod...

Studies on the Interaction between Regulatory Enzymes and Effecters

In order to elucidate the chemical basis of interaction between regulatory enzymes and effecters, various structural analogues of adenosine 5’-monophosphate were investigated for the activating effect on the biodegradative threonine deaminase of Escherichia coli. The mode of activation by each compound was analyzed kinetically in terms of the maximal activation effect and the concentration whic...
