We have developed an efficient production system for porcine pancreatic phospholipase A2 in Saccharomyces cerevisiae (baker's yeast). The cDNA encoding the prophospholipase A2 was expressed under the control of the galactose inducible GAL7 promotor, and secretion was directed by the secretion signals of yeast invertase. This construct yielded up to 6 mg prophospholipase A2 activity per 1 fermentation broth, secreted as a glycosylated invertase prophospholipase A2 hybrid protein. Upon genetically deleting the glycosylation site, the level of secretion decreased to 3.6 mg prophospholipase A2 per 1. Changing the invertase secretion signals for an invertase/alpha-mating factor prepro sequence-fusion increased the secretion level up to 8 mg per 1. The secreted non-glycosylated prophospholipase A2 species was correctly processed. Our results demonstrate the promises and limitations for rational design to obtain high level expression and secretion of heterologous proteins by S. cerevisiae.
