Characterization of the bZip-type transcription factor NapA with reference to oxidative stress response in Aspergillus nidulans.

Microorganisms growing in natural habitats are constantly confronted with a wide variety of external stresses. Here we provide several lines of experimental evidence for the thesis that the filamentous fungus Aspergillus nidulans has a homolog of the AP-1-like bZip transcription factor, which is known to play general roles in oxidative responses in many types of yeast.
