摘要
A recombinant wine yeast strain has been constructed expressing the gene coding for alpha-L-arabinofuranosidase B from Aspergillus niger under the control of the yeast actin gene promoter. The protein is efficiently secreted by the recombinant yeast, allowing its purification and characterisation. The heterologous alpha-L-arabinofuranosidase B Shows similar physicochemical properties to the native enzyme. The wine produced in microvinification experiments using the recombinant yeast presents the same oenological characteristics as obtained with the untransformed strain. The alpha-L-arabinofuranosidase B protein is detected throughout the fermentation.
