Bacteria play a crucial role in producing calcium carbonate minerals, via enzymes including carbonic anhydrase—an enzyme with the capability to hydrolyse CO₂, commonly employed in carbon capture systems. This study describes previously uncharacterised carbonic anhydrase enzyme sequences capable of sequestering CO₂ and subsequentially generating CaCO₃ biominerals and suggests a route to produce carbon negative cementitious materials for the construction industry.
