Part:BBa_K4665120

This part encodes the zinc metalloenzyme carbonic anhydrase derived from the thermophilic bacterium Sulfurihydrogenibium azorense (SazCA). SazCA facilitates the reversible hydration of carbon dioxide to bicarbonate and protons (CO2 + H2O -><- HCO3 + H+) (De Simone et al, 2015). To date, SazCA is the fastest known carbonic anhydrase with an enzymatic efficacy of kcat/KM = 3.5 × 108 M−1 s−1 (De Luca et al., 2015).
