WebJun 25, 2024 · Horseradish peroxidase (HRP) is the most commonly used enzyme because of its high activity, stability, small molecular weight and easy preparation of pure enzyme. It is composed of multiple isoenzymes, with a molecular weight of 40,000 and an isoelectric point of PH3 to 9. The optimum pH for enzyme catalysis varies slightly due to different ... WebHorseradish peroxidase is an oxidoreductase that had been extensively studied along the years and which has shown to be a useful tool in biotechnology. In fact, this enzyme has been used in a huge variety of applications in environmental 6 ( e.g. wastewater remediation) and biological fields 7 ( e.g. DNA sensors).
WebWasabi (Wasabi japonica) and horseradish (Cholearia arnoracia) are used as spices of daily foodstuffs. Allylisothiocyanate (AIT) is a potent component in both plants and occurs by grating them. It is well known that AIT shows inhibitory effect on the growth of food poisoning bacteria and fungi. WebOxidation reactions catalyzed by horseradish peroxidase (HRP) involve the conversion of ferric heme to the ferryl state by hydrogen peroxide (H 2 O 2).As a result, HRP is typically considered unreactive without the presence of H 2 O 2.Herein, we report the first use of histidine (His) and HRP in the presence of daylight and oxygen to initiate photocatalytic …
