Abstract

Summary

A diverse range of heterotrophic bacteria was screened for the presence of carbonic anhydrase (CA) activity, sensitivity to inhibition of growth by acetazolamide (CA inhibitor), and the presence of protein binding monospecific antibody prepared against purified Neisseria sicca CA. CA activity was demonstrated only in strains of and However, all strains, including various isolates of and were sensitive to acetazolamide, when grown in air, and showed serological cross-reaction with CA. Strains of other genera were resistant to acetazolamide. A number of strains including members of the genera and also strongly expressed a gene product(s) immunologically related to CA. The presence of CA cross-reacting proteins, which lack hydrase activity, is discussed in relation to the function of the various mammalian CA isoenzymes.
