The use of CAs in CO2 capture processes for mitigating the global temperature rise has also been investigated more recently. Carbonic anhydrase inhibition/activation: trip of a scientist around the world in the search of novel chemotypes and drug targets. Targeting such enzymes from pathogens may lead to novel anti-infectives. Although it performs a lot of beneficial functions, it can also damage the human body as well, even causing some forms of cancer. Several important physiological and physio-pathological functions are played by CA isozymes present in organisms all over the phylogenetic tree, related to respiration and transport of CO(2)/bicarbonate between metabolizing tissues and the lungs, pH and CO(2) homeostasis, electrolyte secretion in a variety of tissues/organs, biosynthetic reactions, such as the gluconeogenesis and ureagenesis among others (in animals), CO(2) fixation (in plants and algae), etc. Application of carbonic anhydrase inhibitors to increase the penetration of doxorubicin and its liposomal formulation into 2D and 3D triple negative breast cancer cell cultures. Bioorg Med Chem. Epub 2007 Apr 19. Curr Pharm Des. Without this enzyme, the conversion from carbon dioxide to bicarbonate, and vice versa, would be extremely slow, and it would be nearly impossible to carry out life processes, such as photosynthesis in plants and people exhaling carbon dioxide during respiration. One difference is that plant cells obtain carbon dioxide from air and soil instead of producing it.

Among the six genetic families known to date, the α-, β-, γ-, δ-, ζ- and η-CAs, detailed kinetic and X-ray crystallographic studies have allowed a deep understanding of the structure-function relationship in this superfamily of proteins. anhydrase [an-hi´drās] an enzyme that catalyzes the removal of water from a compound. How many carbonic anhydrase inhibition mechanisms exist? CA inhibition has therapeutic applications for drugs acting as diuretics, antiepileptics, antiglaucoma, antiobesity and antitumour agents. published by Portland Press Limited on behalf of the Biochemical Society.  |  An overview of the alpha-, beta- and gamma-carbonic anhydrases from Bacteria: can bacterial carbonic anhydrases shed new light on evolution of bacteria? 2015 Apr;30(2):325-32. doi: 10.3109/14756366.2014.910202.

Alpha-Carbonic Anhydrases from Hydrothermal Vent Sources as Potential Carbon Dioxide Sequestration Agents: Activation of carbonic anhydrases from human brain by amino alcohol oxime ethers: towards human carbonic anhydrase VII selective activators. The CA activation and inhibition mechanisms are also known in detail, with a large number of new inhibitor classes being described in the last years. Astrocytes regulate brain extracellular pH via a neuronal activity-dependent bicarbonate shuttle. Get the latest research from NIH: https://www.nih.gov/coronavirus. Carbonic anhydrases as drug targets--an overview. A metal hydroxide nucleophilic species of the enzyme, and a unique active site architecture, with half of it hydrophilic and the opposing part hydrophobic, allow these enzymes to act as some of the most effective catalysts known in Nature. 2020 Dec;35(1):1923-1927. doi: 10.1080/14756366.2020.1835885. J Orthop Surg Res. At least 16 different alpha-CA isoforms were isolated in mammals, where these enzymes play crucial physiological roles. Some forms of cancer are also accelerated by carbonic anhydrase as well, including ovarian, breast, colon and kidney cancers. J Enzyme Inhib Med Chem. The latter is the active species, acting as a potent nucleophile. USA.gov. CAs are inhibited by two classes of compounds: the metal complexing anions and the sulfonamides and their isosteres (sulfamates, sulfamides etc.) Carbon dioxide is produced as waste from breaking down sugars and fats and in respiration, so it has to be transported through the body to the lungs. Am J Cancer Res. 2016;31(3):345-60. doi: 10.3109/14756366.2015.1122001. A disease caused by this enzyme's activity, but not the enzyme itself, is glaucoma, in which pressure from acidic fluid buildup decreases eyesight over time. Novel insights on saccharin- and acesulfame-based carbonic anhydrase inhibitors: design, synthesis, modelling investigations and biological activity evaluation.

These enzymes are efficient catalysts for the reversible hydration of carbon dioxide to bicarbonate, but at least the alpha-CAs possess a high versatility, being able to catalyze different other hydrolytic processes The catalytic mechanism of the alpha-CAs is understood in detail: the active site consists of a Zn(II) ion co-ordinated by three histidine residues and a water molecule/hydroxide ion. 2007 Jul 1;15(13):4336-50. doi: 10.1016/j.bmc.2007.04.020.

Novel insights on saccharin- and acesulfame-based carbonic anhydrase inhibitors: design, synthesis, modelling investigations and biological activity evaluation. Apart from the zinc binders, some classes of inhibitors anchor to the metal ion coordinated nucleophile, others occlude the entrance of the active site cavity and more recently, compounds binding outside the active site were described. The plant version is found in the liquid part of the cell, while the animal version is found in cell mitochondria.  |  Representatives of the beta-delta-CA family are highly abundant in plants, diatoms, eubacteria and archaea. The structure can be almost completely different since it has a different amino acid sequence, and uses a zinc metal ion, which interacts with the oxygen atoms, also in a different mechanism from that of humans and animals.
