Catechol Oxidase (Diphenol Oxidase)

An enzyme of the oxidoreductase class that catalyzes the reaction between catechol and oxygen to yield benzoquinone and water. It is a complex of copper-containing proteins that acts also on a variety of substituted catechols. EC
Also Known As:
Diphenol Oxidase; Polyphenol Oxidase; Polyphenoloxidase; Oxidase, Catechol; Oxidase, Diphenol; Oxidase, Polyphenol; Oxidases, Diphenol; Diphenol Oxidases; 1,2-Benzenediol:oxygen oxidoreductase

12/01/2001 - "Changes of apple phenolics and polyphenol oxidase activity during cold storage and the biological activity of these phenolics have also been analyzed with reference to the development of quiescent infections during cold storage plus shelf life at room temperature. "
06/01/2015 - "Regarding defense-associated enzyme levels, only following infection did grass grown in Si-amended soil exhibit greater activities of peroxidase and polyphenol oxidase than equivalent inoculated control plants. "
02/01/2006 - "However, gentisic-acid treatments strongly induced polyphenol oxidase activity in cucumber, whereas pathogen infection or SA treatment resulted in a lower induction of this enzyme. "
02/01/2015 - "Additionally, a significantly enhanced accumulation of antioxidant peroxidase (POX) and polyphenol oxidase (PPO) enzymes was observed in the PGPR-pretreated plants with or without pathogen infection in comparison with water or pathogen control. "
07/15/2013 - "Consistent with the observation that the SAR provided the highest level of protection when the time interval between primary infection and challenge inoculation was 10d, the activities of defense-related enzymes such as phenylalanine ammonia lyase (PAL, EC, peroxidase (POD, EC, polyphenol oxidase (PPO, EC, and superoxide dismutase (SOD, EC in systemic tissues also reached the maximum level and were 2.00-2.43 times higher than that of the corresponding controls on the tenth day.
