Ap. Maccabe et D. Ramon, Expression of the Aspergillus nidulans xlnC gene encoding the X-34 endo-xylanase is subject to carbon catabolite repression and pH control, WORLD J MIC, 17(1), 2001, pp. 57-60
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.
