The region encompassing the alpha-galactosidase MELr gene was amplified from Zygosaccharomyces mrakii IFO 1835(T) by inverse-PCR and then sequenced. The nucleotide sequence of this region revealed a single open reading frame of 1410 bp encoding a 470 amino acid protein with a molecular weight of 51,909. The similarity of the deduced mature protein to other yeast alpha-galactosidases was 63.3% to Zygosaccharomyces cidri, 71.5% to Torulaspora delbrueckii, and 70.7-73.9% to Saccharomyces species. The nucleotide and amino acid sequences are deposited in the DDBJ/EMBL/GenBank database under Accession Number AB030209.
