A cDNA was isolated from an Aspergillus aculeatus cDNA library using s
ynthetic oligodeoxyribonucleotide mixtures that corresponded to the in
ternal amino acid (aa) sequence of mature beta-glucosidase 1 (BGL1). A
nalysis of the nucleotide sequence of the cloned cDNA insert revealed
a 2580-bp open reading frame (ORF) that encoded a 860-aa protein. The
deduced aa sequence of the ORF shared sequence similarity with several
BGL from other microorganisms.
