A gene (pel1) encoding pectin lyase (Pel1) was isolated from a shoyu koji mold, Aspergillus oryzae KBN616, and characterized. The structural gene comprised 1,196 bp with a single intron. The ORF encoded 381 amino acids with a signal peptide of 20 amino acids. The deduced amino acid sequence showed high similarity to those of Aspergillus niger pectin lyases and Glomerella cingulata PnlA. The pel1 gene was successfully overexpressed under the promoter of the A. oryzae TEF1 gene. The molecular mass of the recombinant pectin lyase substantially coincided with that calculated based on nucleotide sequence.

A second pectin lyase gene, designated pel2, was isolated from a shoyu koji mold Aspergillus oryzae KBN616 and characterized. The structural gene comprised 1306 bp with three introns. The ORF encoded 375 amino acids with a signal peptide of 19 amino acids. The deduced amino acid sequence showed high similarity to those of A. oryzae Pel1, Aspergillus niger pectin lyases and Glomerella cingulata Pn1A. The pel2 gene was overexpressed under the control of the promoter of the A. oryzae TEF1 gene for purification and enzymatic characterization of its gene product. The gene product exhibited two molecular masses of 48 and 44 kDa due to different degrees of glycosylation. Both proteins had the same pH optimum of 6.0 and temperature optimum of 50 degrees C.
