A simple, reliable, and universal method is demanded for routine determination of carbonic anhydrase (CA) activity, overcoming the limitations previous assays that are inaccurate, complicated, expensive, or limited to a specific enzyme family. The most widely used Wilbur–Anderson assay was modified improve speed, accuracy, precision by employing temperature controllable UV/Vis spectrophotometer...
Two molecular forms of carbonic anhydrase were identified in the rat anterior pituitary gland. Electrophoretic and immunological studies disclosed that the low activity carbonic anhydrase (type B) was associated with the particulate fraction of the pituitary gland and the high activity carbonic anhydrase (type C) was localized in the soluble fraction. The 800 times g pellet contained 50% of the...
A shortage in the zinc supply to spinach (Spinacia oleracea L.) drastically reduced carbonic anhydrase levels with little effect on net CO(2) uptake per unit leaf area, except with the most severe zinc stresses. Under these conditions, carbonic anhydrase was below 10% and photosynthesis 60 to 70% of the control levels. When photosynthesis was measured at a range of CO(2) supply levels, zinc-def...
Carbonic anhydrase IX (CA IX) is a surrogate marker of hypoxia, involved in survival and pH regulation in hypoxic cells. We have recently characterized its interactome, describing a set of proteins interacting with CA IX, mainly in hypoxic cells, including several members of the nucleocytoplasmic shuttling apparatuses. Accordingly, we described complex subcellular localization for this enzyme i...
CONTEXT A serum antibody to carbonic anhydrase II has been reported in patients with Sjögren's syndrome and idiopathic chronic pancreatitis. OBJECTIVE To evaluate cellular immune response to carbonic anhydrase II in patients with Sjögren's syndrome and idiopathic chronic pancreatitis. PATIENTS Idiopathic chronic pancreatitis (n=23), Sjögren's syndrome (n=12), alcoholic chronic pancreatitis ...
OBJECTIVES The relationship between adenosine deaminase and various cancers has been investigated in several studies. However, serum adenosine deaminase activity and carbonic anhydrase and catalase activities in patients with bladder cancer have not previously been reported. Therefore, the aim of this study was to measure serum adenosine deaminase, carbonic anhydrase and catalase activities in ...
1. Patterns of carbon dioxide excretion were investigated in rainbow trout (Salmo gairdneri). 2. The loss of erythrocytic carbonic anhydrase caused by severe anaemia does not affect acid/base regulation or the ability of fish to excrete CO2. 3. Bicarbonate excretion across the saline-perfused gills of trout is significant even though residence time for the saline in the gills is only 1--3 s. CO...
The chemical diversity, binding specificity and propensity to interact with biological targets has inspired many researchers to utilize natural products as molecular probes. Almost all reported carbonic anhydrase inhibitors comprise a zinc binding group in their structure of which the primary sulfonamide moiety (-SO2NH2) is the foremost example and to a lesser extent the primary sulfamate (-O-S...
