| Abstract |
We found that a carbonic anhydrase, YadF, is essential for cell growth in the absence of another carbonic anhydrase, CynT, in Escherichia coli. However, mutant strains lacking both of them grew at high CO2 concentrations (5%), where non-enzymatic mechanisms generate HCO3-. This suggests that these carbonic anhydrases are essential because they maintain HCO3- levels at ambient CO2 concentrations. |
