A cDNA library from Aspergillus niger strain NRRL-3 enriched in sequences glucose oxidase was constructed. An 800 bp cDNA clone isolated from this library was used to screen 12,000 recombinant phages from an EMBL3 genomic library. A 15 kbp DNA segment isolated from this library contained the 1815 bp structural gene for glucose oxidase as well as a short 5'- and a longer 3'-noncoding region. The deduced protein sequence was verified by partial peptide sequencing.
