Substrate specificity of polyphenol oxidase
Critical Reviews in Biochemistry and Molecular Biology, 2020The ubiquitous type-3 copper enzyme polyphenol oxidase (PPO) has found itself the subject of profound inhibitor research due to its role in fruit and vegetable browning and mammalian pigmentation. The enzyme itself has also been applied in the fields of bioremediation, biocatalysis and biosensing.

The effect of polyamide on the extraction of polyphenol oxidase in the leaves and the localization of the enzyme in tea leaf cell were investigated.In the homogenate treated with polyamide, a major part of the enzyme activity appeared in the centrifugal precipitates in the range of l,400×g to 15,000×g, and polyphenol content decreased.

The enzyme polyphenol oxidase (PPO) has been implicated in discoloration of Asian noodles. The recombinant inbred line (RIL) populations, M6/‘Opata 85’, NY18/CC, and ND2603/‘Butte 86’ were used to investigate the distribution, chromosome location, and number of loci involved in wheat (Triticum aestivum L.) PPO. PPO activity was measured by means of the

Polyphenol oxidase and photosynthesis research
Photosynthesis Research, 1995Very briefly, the present state of knowledge on the latent, lumen oriented polyphenol oxidase (PPO) of the chloroplast is reviewed. The location of PPO in the thylakoid membrane was described by D. Arnon 46 years ago. The N-terminus sequence of the spinach enzyme is reported.

Abstract Recent progress in the study of plant polyphenol oxidases is critically reviewed. Two main groups are recognized: the catecholoxidases and the laccases. Their purification, subcellular location and protein properties are described. Attention is also given to their activation and induction, their function and evolution.

Properties of wheat bran polyphenol oxidase
Food / Nahrung, 2004AbstractPolyphenol oxidase (PPO) obtained from wheat bran catalyzed the oxidation of 4‐methyl catechol. Phenolic compounds found naturally in crude extract played role as an endogeneous substrate and activity of crude extract needed correction. Activity versus enzyme concentration gave a linear plot at high substrate concentration whereas a nonlinear ...
