1.1.1.307	D-xylose + NADPH + H+	expression of Texr is inducible by the same carbon sources responsible for the induction of genes encoding enzymes relevant to lignocellulose hydrolysis, suggesting a coordinated expression of intracellular and extracellular enzymes relevant to hydrolysis and metabolism of pentose sugars in Talaromyces emersonii in adaptation to its natural habitat. This indicates a potential advantage in survival and response to a nutrient-poor environment
