Crystal structure and kinetic studies of a tetrameric type II β-carbonic anhydrase from the pathogenic bacterium Vibrio cholerae.
Carbonic anhydrase (CA) is a zinc enzyme that catalyzes the reversible conversion of carbon dioxide to bicarbonate (hydrogen carbonate) and a proton. CAs have been extensively investigated owing to their involvement in numerous physiological and pathological processes. Currently, CA inhibitors are widely used as antiglaucoma, anticancer and anti-obesity drugs and for the treatment of neurologic...
متن کاملCarbonic Anhydrase and Zinc in Plant Physiology
Carbonic anhydrase (CA) (EC: 2.4.1.1) catalyzes the rapid conversion of carbon dioxide plus water into a proton and the bicarbonate ion (HCO3) that can be found in prokaryotes and higher organisms; it is represented by four different families. Carbonic anhydrase is a metalloenzyme that requires Zn as a cofactor and is involved in diverse biological processes including pH regulation, CO2 transfe...
متن کاملInfrared studies on the mechanism of action of carbonic anhydrase.
By accurately measuring the difference infrared spectrum of Cot-equilibrated bovine carbonic anhydrase against the ethoxzolamideor azide-inhibited enzyme, we have been able to obtain the absorption maximum at 2341 cm-l that is due to the asymmetric stretching of the CO2 molecule loosely bound to a hydrophobic surface at the active site of the enzyme. COz dissolved in water absorbs at 2343.5 cm-...
متن کاملCarbonic anhydrase inhibitors: inhibition of Plasmodium falciparum carbonic anhydrase with aromatic/heterocyclic sulfonamides-in vitro and in vivo studies.
A library of aromatic/heterocyclic sulfonamides possessing a large diversity of scaffolds has been assayed for inhibition of the carbonic anhydrase (CA, EC 4.2.1.1) from the malaria parasite Plasmodium falciparum (pfCA). Low micromolar and submicromolar in vitro inhibitors were detected, whereas several compounds showed ex vivo anti-P. falciparum activity, in cell cultures. One derivative, that...
متن کاملCarbonic anhydrase II deficiency syndrome--clinico-pathological, biochemical and molecular studies.
We reported on three unrelated Japanese families with carbonic anhydrase II (CA II) deficiency syndrome. In the present study, the CA II gene was sequenced in the family of a patient with hybrid type renal tubular acidosis whose parents were nonconsanguineous, and a T to G transition at exon 2 was identified. The change results in the substitution of the stop codon (TAG) at position 40 for Tyr ...
