Carbonic anhydrase in marine algae.
An electrometric system for determination of carbonic anhydrase activity was constructed. Enzyme activity was assayed in homogenates of marine macroscopic Chlorophyta, Rhodophyta, and Phaeophyta. Plants surveyed included Ulva expansa (Setchell) Setchell and Gardner, Codium fragile (Suringar) Hariot, Enteromorpha sp., Chaetomorpha torta (Farlow) McClatchie (Chlorophyta); Laurencia papillosa (Gre...
متن کاملUrine pH and carbonic anhydrase activity in the marine dogfish.
EVERAL S years ago it was reported by Smith (I) that the acidity of the urine in both the marine dogfish and sculpin is fixed at about PH 5.7 and cannot be changed by the intravenous administration of sodium bicarbonate, alkaline phosphate or phlorizin. The suggestion was then made that this fixation of urine PH might be related to the fact that in the marine fishes the urine contains large qua...
متن کاملCadmium-Containing Carbonic Anhydrase CDCA1 in Marine Diatom Thalassiosira weissflogii
The Carbon Concentration Mechanism (CCM) allows phytoplakton species to accumulate the dissolved inorganic carbon (DIC) necessary for an efficient photosynthesis even under carbon dioxide limitation. In this mechanism of primary importance for diatoms, a key role is played by carbonic anhydrase (CA) enzymes which catalyze the reversible hydration of CO2, thus taking part in the acquisition of i...
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.
