    摘要: Disclosed are a cloned cDNA and a cloned genomic DNA, both encoding a .beta.-galactosidase polypeptide from Aspergillus niger. Also disclosed are .beta.-galactosidase expression vectors, transformed host cells that overexpress recombinant A. niger .beta.-galactosidase, and A. niger host cell strains with disrupted endogenous .beta.-galactosidase genes. Also disclosed are transgenic non-human mammals that express A. niger .beta.-galactosidase.
