Phenoloxidases in ascidian hemocytes: characterization of the pro-phenoloxidase activating system

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2003
The phenoloxidase (PO) activity of the hemocytes lysate supernatant from three ascidians species, assayed by means of 3-methyl-2-benzothiazolinone hydrazone hydrochloride, have been compared. PO-containing hemocytes were identified by a cytochemical reaction and the enzymatic activity measured by a spectrophotometric assay of lysate supernatant from ...

Temperature regulation of the cryptococcal phenoloxidase

Medical Mycology, 1991
Melanin formation at 37 degrees C has been proposed as a virulence factor in Cryptococcus neoformans. However, whereas catecholamine uptake is maintained at this temperature, phenoloxidase, which catalyses the oxidation of catecholamine to melanin, is severely decreased in most wild type strains cultivated at 37 degrees C.

Phenoloxidases of Aspergillus nidulans

Transactions of the British Mycological Society, 1974
A maximum of five phenoloxidase bands of the tyrosinase type were detected on Polyacrylamide gels after disk electrophoresis of extracts of Aspergillus nidulans . One band could be distinguished from the others because it was thermolabile. At least one band was present in all samples analysed.

Multiple Forms of Phenoloxidase

Journal of Food Science, 1967
SUMMARY— The phenoloxidase system in the tissues of mushrooms, potatoes, and apples was investigated using a polyacrylamide electrophoretic technique. The enzyme system was shown to exhibit the phenomenon of multiple forms.

Phenoloxidase of Mycobacterium leprae

Nature, 1967
INVESTIGATIONS of the metabolism of Mycobacteriumleprae1 have revealed a few of the metabolic characteristics of this micro-organism. Concentrates of M. leprae prepared from lepromatous material actively oxidized 3,4-dihydroxyphenylalanine (DOPA) to pigmented products, in vitro2. Among several strains of mycobactena tested (including M. tuberculosis, M.
