Carbonic anhydrase - Wikipedia
网页An anhydrase is defined as an enzyme that catalyzes the removal of a water molecule from a compound, and so it is this "reverse" reaction that gives carbonic anhydrase its name, because it removes a water molecule from carbonic acid. In the lungs carbonic anhydrase converts bicarbonate to carbon dioxide, suited for exhalation.

Role of Carbonic Anhydrases and Inhibitors in Acid–Base …
网页2019年8月6日 · Carbonic anhydrases (CAs) are ubiquitous metalloenzymes that catalyze one of the most important reactions in life: the interconversion of carbon dioxide (CO 2) and water (H 2 O) to bicarbonate (HCO 3−) and protons (H +).
Carbonic anhydrase, its inhibitors and vascular function
网页2024年1月29日 · A common metalloprotein found in both prokaryotes and eukaryotes, Carbonic Anhydrase (CAs, EC 4.2.1.1) enzymes catalyze the basic biochemical reaction of carbon dioxide hydration, which results in the production of a bicarbonate anion and a proton. Consequently, they are one of the key regulators of cellular pH homeostasis (Supuran, 2016b).
The Carbonic Anhydrases in Health and Disease | SpringerLink
网页2021年10月31日 · Carbonic anhydrase (CA) catalyzes the reversible hydration of carbon dioxide to bicarbonate (CO 2 + H 2 O ↔ HCO 3− + H +), a reaction of such profound importance that the enzyme is seemingly ubiquitous in nature, being represented by seven distinct gene families—α, β, γ, δ, ζ, η, and θ—of which only the α-family is present in human.
Introduction to the carbonic anhydrases | SpringerLink
网页Since the discovery, almost 70 years ago, of the enzyme carbonic anhydrase (CA), which plays an important role in the red blood cell by catalyzing the hydration of carbon dioxide (CO 2 + H 2 O ↔ HCO –3 + H +), a fascinating and complex story has unfolded of three enzyme families performing numerous functions in many different organisms.
Carbonic anhydrase — a universal enzyme of the carbon-based …
网页2017年1月23日 · Carbonic anhydrase (CA) is a metalloenzyme that performs interconversion between CO2 and the bicarbonate ion (HCO3 −). CAs appear among all taxonomic groups of three domains of life. Wide spreading of CAs in nature is explained by the fact that carbon, which is the major constituent of the enzyme’s substrates, is a key element of life on ...
