The recombinant yeast expression plasmid, pSGO2, has been constructed containing a hybrid yeast alcohol dehydrogenase II-glyceraldehyde-3-phosphate dehydrogenase promoter, the glucose oxidase presequence and the mature glucose oxidase coding sequence. When transformed into yeast, this plasmid directs the synthesis and secretion of more than 1.5 g l-1 of active glucose oxidase. Analysis of the yeast-derived enzyme shows extensive N-linked glycosylation in comparison to the A. niger protein. Both proteins show similar specific activities in terms of U mg-1 of protein.
