First report of phenoloxidase and peroxidase activities in two intertidal sea anemone species of Argentina
(University of Modena and Reggio Emilia, 2014-07)
The presence of immune responses within sea anemone species has received little attention, in comparison with coral species, so we decided to investigate the phenoloxidase and peroxidase activities in ectoderm, endoderm ...
Characterization of phenoloxidase activity from spider Polybetes pythagoricus hemocyanin
(Wiley-liss, Div John Wiley & Sons Inc, 2015-10)
Hemocyanin of the spider Polybetes pythagoricus, in addition to its typical role as an oxygen transporter, also exhibits a phenoloxidase activity induced by micellar concentrations of SDS. In the present work, we found the ...
Cresolase, catecholase and laccase activities in haemocytes of the red swamp crayfish
(FISH & SHELLFISH IMMUNOLOGY, 2009)
First evidence of a potential antibacterial activity involving a laccase-type enzyme of the phenoloxidase system in Pacific oyster Crassostrea gigas haemocytes
Phenoloxidases (POs) are a group of copper proteins including tyrosinase, catecholase and laccase. In
several insects and crustaceans, antibacterial substances are produced through the PO cascade, participating in the ...
Phenoloxidase specific activity in the red swamp crayfish procambarus clarkii
(FISH & SHELLFISH IMMUNOLOGY, 2009)
Differential tissue distribution and specificity of phenoloxidases from the Pacific oyster Crassostrea gigas
Phenoloxidases (POs) play a key role in melanin production, are involved in invertebrate immune
mechanisms, and have been detected in different bivalves. Recently, we identified catecholase- and
laccase-like PO activities ...
Phenoloxidase activation in the embryo of the common cuttlefish Sepia officinalis and responses to the Ag and Cu exposure
The prophenoloxidase (proPO) system catalyzing the melanin production is considered as implicated in the innate immune system in invertebrates. The phenoloxidase (PO)-like activity was detected in the cuttlefish embryo ...
Isolation and partial characterization of an extracellular low-molecular mass component with high phenoloxidase activity from Thermoascus aurantiacus
(Academic Press IncSan DiegoEUA, 1999)
