Genetics of a Drosophila phenoloxidase [PDF]
Molecular and General Genetics MGG, 1985 An electrophoretic mobility variant of phenoloxidase in a lz stock of Drosophila melanogaster was identified as the A3 component of the phenoloxidase complex by using two different activators to study enzyme activity-natural activator isolated from pupae and 50% 2-propanol.

Immune properties of invertebrate phenoloxidases
Developmental & Comparative Immunology, 2021 Melanin production from different types of phenoloxidases (POs) confers immunity from a variety of pathogens ranging from viruses and microorganisms to parasites. The arthropod proPO expresses a variety of activities including cytokine, opsonin and microbiocidal activities independent of and even without melanin production.

Evolution, Structure, And Function Of Phenoloxidase In The Pea Aphid Acyrthosiphon Pisum [PDF]
, 2012 Phenoloxidases (monophenol monooxygenase, EC 1.14.18.1; catechol oxidase, EC 1.10.3.1) are a group of enzymes with copper cofactors that produce reactive quinones and are part of the melanin synthesis pathway, both of which have important roles in ...

Recent findings on phenoloxidases in bivalves [PDF]
Marine Pollution Bulletin, 2017 The production of melanin is a complex process involving biochemical cascades, such as the pro-phenoloxidase (proPO) system, and enzymes, such as phenoloxidases (POs). Different studies have shown a strong correlation between the decrease in PO activities and the occurrence of diseases in bivalve invertebrates, leading to mortalities in the host ...

Phenoloxidase activity and organic carbon dynamics in historic Anthrosols in Scotland, UK [PDF]
, 2021 Phenolic compounds are chemical precursor building blocks of soil organic matter. Their occurrence can be inhibitory to certain enzymes present in soil, thereby influencing the rate of decomposition of soil organic matter. Microbe-derived phenoloxidases (

Phenoloxidase is involved in the immune reaction of Helix lucorum to parasitic infestation by dicrocoeliid trematode [PDF]
, 2021 Introduction. Phenoloxidases are known to play a role in the immune defences of arthropods and molluscs. In the invertebrates, phenoloxidases mediate three major physiologically important processes: sclerotization, wound healing, and defence reactions ...

Adipokinetic hormone enhances nodule formation and phenoloxidase activation in adult locusts injected with bacterial lipopolysaccharide [PDF]
, 2003 Interactions between the locust endocrine and immune systems have been studied in vivo in relation to nodule formation and activation of the prophenoloxidase cascade in the haemolymph.

Changes in lipophorins are related to the activation of phenoloxidase in the haemolymph of Locusta migratoria in response to injection of immunogens [PDF]
, 2003 In Locusta migratoria, activation of phenoloxidase in the haemolymph in response to injection of laminarin is age-dependent: being absent in fifth instar nymphs and newly emerged adults, and only becoming evident four days after the final moult.
