We provide a kinetic characterization of (Na+, K+)-ATPase activity in a posterior gill microsomal fraction from the grapsid crab Goniopsis cruentata. (Na+, K+)-ATPase activity constitutes 95% of total ATPase activity, and sucrose density centrifugati

Flight dispersal represents a key aspect of the evolutionary and ecological success of insects, allowing escape from predators, mating, and colonization of new niches. The huge energy demand posed by flight activity is essentially met by oxidative ph

Effect of salinity on modulation by ATP, protein kinases and FXYD2 peptide of gill (Na+, K+)-ATPase activity in the swamp ghost crab Ucides cordatus (Brachyura, Ocypodidae)

Autor: Carlos Frederico Leite Fontes, Rogério O. Faleiros, Daniela P. Garçon, Francisco de Assis Leone, Cintya M. Moraes, John Campbell McNamara, Malson Neilson de Lucena, Leonardo M. Fabri

The gill (Na+, K+)-ATPase is the main enzyme that underpins osmoregulatory ability in crustaceans that occupy biotopes like mangroves, characterized by salinity variation. We evaluated osmotic and ionic regulatory ability in the semi-terrestrial mang

Osmotic and ionic regulation, and modulation by protein kinases, FXYD2 peptide and ATP of gill (Na+, K+)-ATPase activity, in the swamp ghost crab Ucides cordatus (Brachyura, Ocypodidae)

We analyzed the modulation by exogenous FXYD2 peptide and by endogenous protein kinases A and C, and Ca2+-calmodulin-dependent kinase, of gill (Na+, K+)-ATPase activity in the semi-terrestrial mangrove crab Ucides cordatus after 10-days acclimation t

Polyamines regulate phosphorylation–dephosphorylation kinetics in a crustacean gill (Na+, K+)-ATPase

Autor: Carlos Frederico Leite Fontes, Francisco A. Leone, Daniela P. Garçon, John Campbell McNamara, Malson N. Lucena

Publikováno v: Molecular and Cellular Biochemistry. 429:187-198

Aiming to clarify the mechanism of inhibition of (Na+, K+)-ATPase activity by polyamines, we examined the effects of exogenous putrescine, spermidine, and spermine on the kinetic behavior of phosphoenzyme-linked partial reactions using a microsomal g

Conformational states of the pig kidney Na+/K+-ATPase differently affect bufadienolides and cardenolides: A directed structure-activity and structure-kinetics study

There is a renewed interest in the Na+/K+-ATPase (NKA, EC 3.6.3.9) either as a target for new therapeutic uses or for understanding the putative pathophysiological role of its mammalian endogenous ligands. Recent data indicate that bufalin binds to t

Cisplatin and other platinum-containing drugs have played a crucial role in anticancer treatments for over 30 years. However, treatment with cisplatin may cause serious side effects, such as myelosuppression, nausea, ototoxicity, nephrotoxicity, and
