Unique Regulatory Mechanism for d-Galactose Utilization in Aspergillus nidulans ▿ †

By Ulla Christensen, Birgit S. Gruben, Susan Madrid, Harm Mulder, Igor Nikolaev and Ronald P. de Vries


This study describes two novel regulators, GalX and GalR, that control d-galactose utilization in Aspergillus nidulans. This system is unique for A. nidulans since no GalR homologs were found in other ascomycetes. GalR shares significant sequence identity with the arabinanolytic and xylanolytic regulators AraR and XlnR, but GalX is more distantly related
