Structural and biochemical correlates of Na+,K+‐ATPase driven ion uptake across the posterior gill epithelium of the true freshwater crab, Dilocarcinus pagei (Brachyura, Trichodactylidae)

Abstract: To better comprehend the structural and biochemical underpinnings of ion uptake across the gills of true freshwater crabs, we performed an ultrastructural, ultracytochemical and morphometric investigation, and kinetically characterized the Na(+),K(+)-ATPase, in posterior gill lamellae of Dilocarcinus pagei. Ultrastructurally, the lamellar epithelia are markedly asymmetrical: the thick, mushroom-shaped, proximal ionocytes contain elongate mitochondria (41% cell volume) associated with numerous (≈14 µm² membrane… Show more

“…Vários pesquisadores tem focado seus esforços no estudo da capacidade da (Na + , K + )-ATPase em hidrolisar o p-nitrofenilfosfato (PNFF) (GACHE et al, 1977;GLYNN, 1985;BERBERIAN & BEAUGÉ, 1992;SPECHT et al, 1997;FURRIEL et al, 2001;HOMAREDA & USHIMARU, 2005). Entretanto, existem controvérsias a respeito do mecanismo de reação da enzima quando esse substrato não fisiológico é utilizado.…”
