The mechanism of induction of secreted
beta-galactosidase
was studied in the filamentous fungus Penicillium canescens.
L-Arabinose
and its metabolite L-arabitol induce the synthesis of the enzyme. Apart from
beta-galactosidase
, L-arabinose induces the synthesis of other extracellular carbohydrolases including alpha-L-arabinofuranosidase. Increasing L-arabinose concentration above 1 mM or addition of other carbon sources results in carbon catabolite repression of the synthesis of the secreted enzymes. The data suggest that arabinofuranosidase can regulate the synthesis of secreted enzymes in P. canescens, thus controlling the level of free L-arabinose.
