Description générale

Carbonic Anhydrase is a metalloenzyme with zinc. The active site of carbonic anhydrase contains three conserved histidine residues (His94, His96 and His119).

Application

Carbonic Anhydrase has been used:
  • as a component of nine-protein mixture for the comparative proteomic mass spectrometry analysis of bovine brain samples
  • as a molecular marker in gel filtration chromatography
  • as a standard protein to test the recovery of CMA/20 microdialysis probe

Actions biochimiques/physiologiques

Carbonic anhydrase is essential for the reversible hydration of carbon dioxide. It is also crucial for the physiological processes including respiration, ion transport, acid–base balance, lipid and carbohydrate metabolic pathways. Carbonic anhydrase participates in electrolyte secretion and in the carbon dioxide fixation.

Définition de l'unité

One collagen digestion unit (CDU) liberates peptides from collagen from bovine achilles tendon equivalent in ninhydrin color to 1.0 μmole of leucine in 5 hours at pH 7.4 at 37 °C.

The carbonic anhydrases enzymes (CAs, EC 4.2.1.1) are zinc containing metalloproteins, which efficiently catalyse the reversible conversion of carbon dioxide to bicarbonate and release proton. These enzymes are essentially important for biological system and play several important physiological and patho-physiological

Unlike all other currently available sampling techniques, microdialysis allows the continuous recovery of dialysed fluid from the interstitial space of living tissue. Microdialysis has been extensively used to study small molecules such as neurotransmitters, metabolites and drugs in the brain

Dependent on concise, predefined protein sequence databases, traditional search algorithms perform poorly when analyzing mass spectra derived from wholly uncharacterized protein products. Conversely, de novo peptide sequencing algorithms can interpret mass spectra without relying on reference databases. However, such algorithms

This work presents a study of industrially applicable techniques to obtain a biologically supported carbon dioxide capture system, based on the extraction of carbonic anhydrase from bovine blood. Carbonic anhydrase is a metalloenzyme which catalyzes the reversible hydration of carbon

While cytoplasmic aggregation of TDP-43 is a pathological hallmark of amyotrophic lateral sclerosis and frontotemporal dementia, how aggregates form and what drives its nuclear clearance have not been determined. Here we show that TDP-43 at its endogenous level undergoes liquid-liquid
