In this study, in silico analysis of the Caenorhabditis elegans genome revealed six genes (cah-1, cah-2, cah-3, cah-4, cah-5, and cah-6) possibly encoding ? class CAs (carbonic anhydrase). Real-time RT-PCR analysis revealed the temporal expression pattern of each gene, as well as changes in expression levels under different atmospheric conditions (stress). Cah-3 and cah-4 showed the highest levels of transcript accumulation, while most genes responded to the stress conditions. Yeast complementation showed that cah-3 was able to complement the function of Saccharomyces cerevisiae CA (NCE103) in vivo. Recombinant CAH-3, CAH-4a and CAH-5 enzymes, expressed in Escherichia coli were used for in vitro measurement of CA activity. However, in vitro activity was only detectable for CAH-4a. RNAi by feeding was performed on wild-type C. elegans for all genes. The worms were examined for a visible phenotype under normal and stress conditions (pH, CO(2)/O(2)). Silencing cah-3 and cah-4 may reduce the life-span of the worms (at 22 °C).
