Carbonic anhydrase is involved in calcification by the benthic foraminifer <i>Amphistegina lessonii</i>

Calcification acidifies the microenvironment of a benthic foraminifer (Ammonia sp.)

Gastric 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...

Renal Tubular Acidosis, Osteopetrosis, and Cerebral Calcification: A Rare Syndrome Caused by Carbonic Anhydrase II Deficiency

A 7‐year, 10‐month‐old boy, product of a consanguineous marriage, presented with short stature and a recent fracture of left forearm following a trivial trauma. There was no significant family history. His height was 103 cm (−3.7 standard deviation) [Table 1]. He had dysmorphic facies such as prominent forehead, thick lower lip, and blue sclera. He had 24 teeth; his temporary teeth had not shed...

Characterization and role of carbonic anhydrase in the calcification process of the azooxanthellate coral Tubastrea aurea

In zooxanthellate corals, the photosynthetic fixation of carbon dioxide and the precipitation of CaCO3 are intimately linked both spatially and temporally making it difficult to study carbon transport mechanisms involved in each pathway. When studying Tubastrea aurea, a coral devoid of zooxanthellae, we can focus on carbon transport mechanisms involved only in the calcification process. We perf...

Internal carbonic anhydrase activity in the tissue of scleractinian corals is sufficient to support proposed roles in photosynthesis and calcification.

Reef-building corals import inorganic carbon (Ci) to build their calcium carbonate skeletons and to support photosynthesis by the symbiotic algae that reside in their tissue. The internal pathways that deliver Ci for both photosynthesis and calcification are known to involve the enzyme carbonic anhydrase (CA), which interconverts CO2 and HCO3 (-). We have developed a method for absolute quantif...
