Abstract
Expression of the Aspergillus nidulans xylanase gene xlnC is subject to reg ulation by carbon catabolite repression and ambient pH. In the presence of glucose, xlnC transcription is repressed by the zinc finger transcription f actor CreA. These data have been confirmed using the extremely derepressed mutant creA(d)30. Expression of xlnC is elevated at alkaline ambient pH and also in alkalinity-mimicking A. nidulans mutants.
