Abstract


High levels of active glycolate oxidase from spinach (GO) and active catalase T from Saccharomyces cerevisiae (catT) have been co-produced in the methylotrophic yeast Pichia pastoris (Pp). In sequential rounds of transformation using two selectable markers, multiple copies of the genes encoding GO and catT were integrated into the Pp chromosome under control of the methanol inducible alcohol oxidase I promoter, resulting in a strain designated MSP8.6. MSP8.6 is a second-generation biocatalyst used for the conversion of glycolate to glyoxylate in the presence of a reaction component which inhibits endogenous Pp catalase. This work demonstrates a significant advance in the utility of recombinant Pp for commercial bioprocess development.
