ABSTRACT:
Polypeptides that are synthesized or expressed directly in microorganisms, include an amino acid sequence that is homologous to at least a portion of gp70 envelope protein of FELV, and are immunogens that elicit or prime a humoral response in cats and immunize cats against FeLV infection. The microbially produced polypeptides are exemplified by a group of E. coli-expressed fusion proteins that comprise a portion of the trp leader peptide and a portion of the trp E protein fused to various portions of a subgroup B gp70 envelope protein. The synthesized polypeptides are exemplified by polypeptides that are homologous to segments of the hydrophilic domains of the gp70 protein.
