ABSTRACT:
Methods and compositions are provided for the efficient production of a polypeptide having immunological reactivity corresponding to that of naturally-occurring envelope glycoproteins of feline leukemia virus. A DNA construct including a replication system recognized by yeast, and a viral envelope protein gene under the transcriptional control of a yeast promoter, and terminator is provided. By transforming a yeast host with the DNA construct, enhanced yields of the product may be obtained.
Saccharomyces carlsbergensis strains 2150-2-3 (pCP-envB-R) and 2150-2-3 (pCP-envA-R) were deposited at the American Type Culture Collection on July 18, 1984, and granted accession nos. 20720 and 20721, respectively.
