Erythrocyte high and low activity forms within a given species usually show greater than 50% sequence identity; for example, equine CA-I and CA-II forms only show 55% identity (Wendorff, 1985). 2003). Carbonate Dehydratase, CATH Classification (v. 3.2.0): Optimal pH: 7.0-7.5 (Demir et al. A hydrogen bonded network, linked to the zinc-bonded water molecule and these histidines either directly or indirectly, includes 28-Ser, 91-Glu, 105-Glu, 106-His, 116-His, 193-Tyr, 198-Thr, 208-Trp, and 223-Asn. STBB0728K9 - enter the lot number STBB0728 without the filling-code CA-VA and CA-VB are mitochondrial. The carbonic anhydrase of vertebrates (the ‘high activity’ isoenzyme of mammals) is found in many ion‐transporting epithelia, but its role in them is still uncertain. ) on Activities of Human Red Blood Cell Carbonic Anhydrase Isoenzymes The carbonic anhydrases (or carbonate dehydratases) form a family of enzymes that catalyze the interconversion between carbon dioxide and water and the dissociated ions of carbonic acid (i.e. Learn about our remote access options, Department of Biochemistry.

It was inferred that a catalyst was present in blood that could dehydrate bicarbonate and allow it to escape as CO2 (Stadie and O’Brien 1933). CA-VI is secreted in saliva.

Comparative Biochemistry and Physiology Part A: Physiology. 50,070 cm-1 M-1 (Theoretical) Hypohidrosis‐related symptoms in pediatric epileptic patients with topiramate. Number of times cited according to CrossRef: Polymorphism in the CAVI gene, salivary properties and dental caries. Erythrocyte CAs, CA-I and CA-II, are most well known. Reproduction of any materials from the site is strictly forbidden without permission. 2009). Virchows Archiv A Pathological Anatomy and Histopathology. Immunohistochemical study of carbonic anhydrase in mixed tumours and adenomas of sweat and sebaceous glands. The discovery that carbonic anhydrase may also catalyse other reactions raises the possibility that the enzyme may have other roles in metabolic pathways (e.g., in certain dehydrogenation reactions). 2. Ultrastructural immunocytochemical localization of carbonic anhydrase in normal and calcitonin‐treated chick osteoclasts. Immunohistochemical localization of carbonic anhydrase I and II in submandibular salivary glands of the mouse, rat, hamster and guinea pig. Carbonic anhydrase isoenzymes in the rat kidney. Erythrocyte high and low activity forms within a given species usually show greater than 50% sequence identity; for example, equine CA-I and CA-II forms only show 55% identity (Wendorff et al.1985). It is not possible to define the role of the ‘low activity’ isoenzyme at present, but attention is drawn to the possibility that it is concerned in the handling of the products of microbial fermentation, such as ammonia and organic acids, by the large intestines and ruminant forestomach.
