Reinvestigation of Purification of Phenoloxidase from Larvae of Housefly

Agricultural and Biological Chemistry, 1981
Phenoloxidase (Diphenoloxidase EC 1.10.3.1) was purified from an aqueous extract of the larvae of the housefly Musca domestica vicina Maquart by a procedure involving affinity chromatography on a Sepharose 4B derivative of p-aminobenzoic acid and ethylene diamine, Sepharose 4B and Sephadex G-200 gel filtrations.

Phenoloxidase is an important component of the defense against Aeromonas hydrophila infection in a crustacean, Pacifastacus leniusculus

, 2007
The melanization cascade, in which phenoloxidase is the terminal enzyme, appears to play a key role in recognition of and defense against microbial infections in invertebrates.

Evaluation of Galleria mellonella larvae as model for testing the virulence factors following infection with the human pathogenic fungi Candida albicans and Aspergillus fumigatus [PDF]

Egyptian Journal of Cancer and Biomedical Research
Background: Testing microbial virulence in mammals is a prerequisite before applying therapeutic agents to humans. However, conducting experiments in mammalian models is expensive and requires ethical considerations.

Phenoloxidase and cytotoxicity in the compound ascidian Botryllus schlosseri

Developmental & Comparative Immunology, 1998
The vacuoles of morula cells (MC) of the colonial ascidian Botryllus schlosseri contain phenoloxidase (PO). As the release of their vacuolar content at the border of incompatible contacting colonies is associated with the formation of necrotic masses which characterize the rejection reaction, the role of PO in Botryllus cytotoxicity was investigated ...

Nature of latent phenoloxidase complex in the prepupae of housefly and its physiological significance

, 1972
In the process of metamorphosis of the housefly, Musca domestica vicina Macquart, phenoloxidase undergoes a sharp fluctuation as shown in Fig.1. The high activity observed at the final stage of larval development disappears completely in the prepupae ...

The shrimp miRNAs involved in apoptosis, phagocytosis and pro- phenoloxidase system.

, 2012
(A) The miRNA expression profiles in responses to the inhibition or activation of apoptosis, phagocytosis or phenoloxidase, respectively. The miRNAs of shrimp without immune inhibitor or activator were used as controls. Missing, not detected.

Purification and properties of phenoloxidase from spinach leaves.

Agricultural and Biological Chemistry, 1989
A phenoloxidase from spinach leaves was extensively purified to homogeneity. The molecular weight of the purified enzyme was 150,000 by gel filtration, and 40,000 by SDS-polyacrylamide gel electrophoresis. The enzyme contained 2 atoms of copper per 150,000 of molecular weight. The optimum pH of the enzyme action is near 6.5.
