BioAssay: AID 677270

Inhibition of Sulfurihydrogenibium yellowstonense YO3AOP1 alpha-carbonic anhydrase-catalyzed CO2 hydration reaction preincubated for 15 mins by stopped flow CO2 hydrase assay

The newly discovered thermophilic bacterium Sulfurihydrogenibium yellowstonense YO3AOP1 encodes an alpha-carbonic anhydrases (CAs, EC 4.2.1.1) which is highly catalytically active and thermostable. Here we report the inhibition of this enzyme, denominated SspCA, with inorganic and complex anions and other molecules interacting with zinc proteins. SspCA was inhibited in the micromolar range by more ..

Description:
Title: Anion inhibition studies of an alpha-carbonic anhydrase from the thermophilic bacterium Sulfurihydrogenibium yellowstonense YO3AOP1.

Abstract: The newly discovered thermophilic bacterium Sulfurihydrogenibium yellowstonense YO3AOP1 encodes an alpha-carbonic anhydrases (CAs, EC 4.2.1.1) which is highly catalytically active and thermostable. Here we report the inhibition of this enzyme, denominated SspCA, with inorganic and complex anions and other molecules interacting with zinc proteins. SspCA was inhibited in the micromolar range by diethyldithiocarbamate, sulfamide, sulfamic acid, phenylboronic and phenylarsonic acid, trithiocarbonate and selenocyanide (K(I)s of 4-70 muM) and in the submillimolar one by iodide, cyanide, (thio)cyanate, hydrogen sulfide, azide, nitrate, nitrite, many complex anions incorporating heavy metal ions and iminodisulfonate (K(I)s of 0.48-0.86 mM). SspCA was not substantially inhibited by bicarbonate and carbonate, hydrogensulfite and peroxidisulfate (K(I)s in the range of 21.1-84.6mM). The exceptional thermostability and lack of strong affinity for hydrogensulfide, bicarbonate, and carbonate make this enzyme an interesting candidate for biotechnological applications of enzymatic CO(2) fixation.
