Abstract
Abstract A process for expression of a gene, foreign to the host organism, coding for a protein in a suitable vehicle which comprises taking said gene and fusing it in the correct orientation relative to a transcriptional initiation region present in said vehicle, and inserting said vehicle into a eukaryotic host. Via the subject process, the gene for chicken ovalbumin is expressed in the yeast Saccharomyces cerevisiae. Chicken ovalbumin can be used in the food, i.e., baking, industry and also as a protein supplement for animals.
