BioAssay: AID 691715

Activity of Sulfurihydrogenibium yellowstonense YO3AOP1 recombinant CA expressed in Escherichia coli BL21(DE3) after 15 mins by phenol red staining based stopped flow CO2 hydration assay

The alpha-carbonic anhydrase (CA, EC 4.2.1.1) from the newly discovered thermophilic bacterium Sulfurihydrogenibium yellowstonense YO3AOP1 (SspCA) was investigated for its activation with a series of amino acids and amines. D-His, L-Phe, L-Tyr, L- and D-Trp were the most effective SspCA activators, with activation constants in the range of 1-12 nM, whereas L-His, L/D-DOPA, D-Tyr, and several more ..

Description:
Title: The first activation study of a bacterial carbonic anhydrase (CA). The thermostable alpha-CA from Sulfurihydrogenibium yellowstonense YO3AOP1 is highly activated by amino acids and amines.

Abstract: The alpha-carbonic anhydrase (CA, EC 4.2.1.1) from the newly discovered thermophilic bacterium Sulfurihydrogenibium yellowstonense YO3AOP1 (SspCA) was investigated for its activation with a series of amino acids and amines. D-His, L-Phe, L-Tyr, L- and D-Trp were the most effective SspCA activators, with activation constants in the range of 1-12 nM, whereas L-His, L/D-DOPA, D-Tyr, and several biogenic amines/catecholamines were slightly less effective activators (K(A) in the range of 37 nM-0.97 muM). The least effective SspCA activator was d-Phe (K(A) of 5.13 muM). The thermal stability, robustness and very high catalytic activity of SspCA make this enzyme an ideal candidate for biomimetic CO(2) capture processes.
