Carbonic anhydrase under pressure
Investigations of the rapid enzyme carbonic anhydrase have now been extended by crystallographic analysis at high CO2 pressures to examine the movements of water molecules in different steps of the catalysis. The rate of catalysis seems well explained by the assembled observations.
متن کاملGastric Carbonic Anhydrase In
Davenport and Fisher (1938) reported the discovery DOGS P School of Medicine of large amounts of carbonic anhydrase in the gastric mucosa of cats, rats and rabbits. Davenport (1939) demonstrated that carbonic anhydrase is present in high concentration in the parietal cells and in lower concentration in the cells of the surface epithelium of the gastric mucosa of cats and rats. When those invest...
متن کامل[Influence of Diamox (acetazolamide sodium) upon inner ear and histochemical study of carbonic anhydrase].
A study was made on the influence of Diamox (acetazolamide sodium) upon inner ear tissue and inner ear fluid, for this drug has been in use for glaucoma for its depressive effect upon the intraocular pressure. On an assumption of the presence of carbonic anhydrase in stria vascularis, widely recognized site of secretion of endolymph, histochemical demonstration of the enzyme was also attempted ...
متن کاملHistochemical distribution of carbonic anhydrase in rat and rabbit lacrimal gland.
PURPOSE The purpose of this study was to examine the histochemical distribution of carbonic anhydrase (CA) in lacrimal glands from rats and rabbits; and to determine if age- and/or sex-related differences exist in the amount and distribution of CA in the rat lacrimal gland. METHODS Lacrimal glands from young (3-12 wk) and aged (2-2.5 yr), male and female F344 rats and male rabbits were fixed ...
متن کاملCarbonic anhydrase in human platelets.
The carbonic anhydrase activity of human platelets was investigated by measuring the kinetics of CO2 hydration in supernatants of platelet lysates by using a pH stopped-flow apparatus. An average carbonic anhydrase concentration of 2.1 microM was determined for pellets of human platelets. Analysis of the kinetic properties of this carbonic anhydrase yielded a Km value of 1.0 mM, a catalytic-cen...
