LITERATURE
physiological function
-
induction of gene expression of the alpha-L-arabinofuranosidase encoding genes abf1, abf2, and abf3 and also bxl1, which encodes a beta-xylosidase with a separate alpha-L-arabinofuranosidase domain and activity, by L-arabinitol is strongly enhanced in a DELTAlad1 strain lacking L-arabinitol dehydrogenase activity and severely impaired in an aldose reductase DELTAxyl1 strain, suggesting a cross talk between L-arabinitol and the aldose reductase XYL1 in alpha-L-arabinofuranosidase gene expression
