The Aspergillus nidulans xylanase genes xlnA and xlnB are subject to regulation by ambient pH via the zinc finger transcription factor PacC. In the presence of D-xylose, xlnA is expressed under conditions of alkaline ambient pH while xlnB is expressed at acidic ambient pH. These data have been confirmed for acidity- and alkalinity-mimicking A. nidulans mutants. In nature, many microbes are exposed to large variations in ambient pH and thus require both an efficient pH homeostatic system and a regulatory mechanism which ensures that those molecules exposed to the environment (such as certain per-meases, small metabolites, and extracellular enzymes) are only produced under appropriate pH conditions. The ascomycete Aspergillus nidulans is able to grow over a wide pH range (14). The regulatory circuit controlling pH regulation in this micro-organism has been analyzed both genetically and molecularly. As an example, this system regulates the secretion of alkaline phosphatase in alkaline growth conditions and acid phospha-
