Expression and localization of carbonic anhydrase and ATPases in the symbiotic tubeworm Riftia pachyptila.
The symbiotic tubeworm Riftia pachyptila needs to fuel its chemoautotrophic symbiotic bacteria with inorganic carbon. CO(2) is transported from the surrounding water to the bacteriocytes located in the trophosome, through the branchial plume and the body fluids. Previous studies have demonstrated the implication of carbonic anhydrase (CA) and proton pumps (ATPases) at various steps of CO(2) tra...
متن کاملIndomethacin reproducibly induces metamorphosis in Cassiopea xamachana scyphistomae
Cassiopea xamachana jellyfish are an attractive model system to study metamorphosis and/or cnidarian-dinoflagellate symbiosis due to the ease of cultivation of their planula larvae and scyphistomae through their asexual cycle, in which the latter can bud new larvae and continue the cycle without differentiation into ephyrae. Then, a subsequent induction of metamorphosis and full differentiation...
متن کاملBlood carbonic anhydrase activity in the newborn.
Logan, R. W., Crooks, S. M., Hutchison, J. H., and Kerr, M. M. (1973). Archives of Disease in Childhood, 48, 256. Blood carbonic anhydrase activity in the newborn. Erythrocyte carbonic anhydrase activity was measured in 7 adults, 12 mature newborn infants, 12 preterm low birthweight infants, 9 'dysmature' infants, 33 infants with the respiratory distress syndrome (RDS), and 5 infants who had re...
متن کاملIdentification and localization of carbonic anhydrase in two chlorella species.
Carbonic anhydrase (CA) activity and localization have been examined in two species of the eukaryotic green alga Chlorella. Mass spectrometric and potentiometric assays of CA activity indicate that C. ellipsoidea contains very little extracellular CA activity whereas C. saccharophila exhibits significant extracellular activity when grown at alkaline pH values. Extracellular CA activity appears ...
متن کاملQuantification of extracellular carbonic anhydrase activity in two marine diatoms and investigation of its role.
Many microalgae induce an extracellular carbonic anhydrase (eCA), associated with the cell surface, at low carbon dioxide (CO2) concentrations. This enzyme is thought to aid inorganic carbon uptake by generating CO2 at the cell surface, but alternative roles have been proposed. We developed a new approach to quantify eCA activity in which a reaction-diffusion model is fit to data on (18)O remov...
