Carbonic anhydrase in the vitreous body.
REVIEWS of some recent literature concerning the biochemistry of the vitreous body contain no references to the presence of enzymes (Bellows, 1952, 1953; von Sallmann, 1953, 1954; McLean, 1954). However, the possibility of the existence of enzymes in the vitreous body has not been overlooked. Lepine (1870) reported that the vitreous of dogs, rabbits, and frogs contained a substance which caused...
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 کاملCarbonic 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 کاملMeasurement of carbonic anhydrase activity of blood at body temperature.
Most measurements of blood carbonic anhydrase activity recorded in the literature have been made by the method of Meldrum and Roughton (1) or some modification of it. These procedures are carried out in a cold water bath at 10” or below. This temperature is disadvantageous technically, and, moreover, affords no direct information as to the activity of the enzyme at mammalian body temperature; i...
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...
