WebHistorical Perspective. The term phenoloxidase is used today to encompass three main families of unrelated oxidising enzymes: PRXs, PPOs, and LACs. However, the definition of phenoloxidase has evolved with time, technologies, and model organisms. In plant and fungal organisms, phenoloxidases refer to LACs, sometimes including PPOs and even … Webphenoloxidase translation in English - French Reverso dictionary, see also 'phenomenally, phenomena, phoenix, photo id', examples, definition, conjugation

Here, we show that phenoloxidase activity and melanization are important for the immune defense toward a highly pathogenic bacterium, Aeromonas hydrophila, in the freshwater crayfish, …
Phenoloxidase system is a major defense system in many invertebrates which ultimately leads to melanization of pathogens and damaged tissues. The process of melanization depends on activation of the enzyme phenoloxidase (PO) which is controlled by the prophenoloxidase (proPO) activation system. During activation of the proPO cascade, many other immune reactions are produced, such as cyt…
