Some properties of active and latent catechol oxidase of mushroom
Acta Agrobotanica, 2013 Latent form of mushroom catechol oxidase was activated by O,1% sodium dodecyl sulfate (SDS). Catalytic power of the latent form, calculated from the kinetic parameters was 1,8 times higher than that of active one.

Identification of Catechol as a New Marker for Detecting Propolis Adulteration
Molecules, 2014 Adulteration of propolis with poplar extract is a serious issue in the bee products market. The aim of this study was to identify marker compounds in adulterated propolis, and examine the transformation of chemical components from poplar buds to propolis.

Beyond brown: Polyphenol oxidases as enzymes of plant specialized metabolism
Frontiers in Plant Science, 2015 Most cloned and/or characterized plant polyphenol oxidases (PPOs) have catechol oxidase activity (i.e. they oxidize o-diphenols to o-quinones) and are localized or predicted to be localized to plastids.

Bananas decrease acetaminophen potency in in vitro assays. [PDF]
PLoS ONE, 2018 Edible portions of bananas contain high levels of polyphenol oxidase, which catalyzes reactions in the melanin formation pathway. Tyrosine, a physiological substrate of polyphenol oxidase, has an analogous structure to acetaminophen.

MONOAMINE OXIDASE AND CATECHOL- O-METHYLTRANSFERASE INHIBITORS
Medical Clinics of North America, 1999 Despite advances in the treatment of PD, there remain significant unmet therapeutic needs. This is particularly true at the later stages of the disease when dopaminergic therapy is complicated by motor fluctuations and dyskinesias. Inhibition of dopamine metabolism is a valuable adjunct to exogenous dopaminergic replacement.

eNeurologicalSci, 2020 Background: Dopamine replacement therapy is an established treatment for motor symptoms of Parkinson's disease, but its long-term use is often limited by the eventual development of motor complications, including levodopa-induced dyskinesia.
