POLYPEPTIDE ANTIGENS OF MYCOBACTERIUM BOVIS

摘要

The invention provides a synthetic polypeptide having at least one antigenic property of the MPB-70 protein of at least one strain of (Mycobacterium bovis), said polypeptide of Formula (I) comprising an amino acid sequence selected from Formulae Seq. ID Nos 1-14: Seq. ID No 1: X-Glu-Tyr-Ala-Ala-Ala-Asn-Pro-Thr-Gly-Pro-Ala-Ser-Val-Gln-Gly-Y; Seq. ID No 2: X-Met-Ser-Gln-Asp-Pro-Val-Ala-Val-Ala-Ala-Ser-Asn-Asn-Pro-Y; Seq. ID No 3: X-Pro-Glu-Leu-Thr-Thr-Leu-Thr-Ala-Ala-Leu-Ser-Gly-Gln-Leu-Asn-Pro-Gln-Y; Seq. ID No 4: X-Val-Val-Ala-Gly-Gln-Thr-Ser-Pro-Ala-Asn-Val-Y; Seq. ID No 5: X-Pro-Gln-Val-Asn-Leu-Val-Asp-Thr-Leu-Asn-Ser-Gly-Gln-Tyr-Ser-Val-Y; Seq. ID No 6: X-Phe-Ala-Pro-Thr-Asn-Ala-Ala-Phe-Ser-Y; Seq. ID No 7: X-Pro-Ala-Ser-Thr-Leu-Asp-Glu-Leu-Thr-Asn-Y; Seq. ID No 8: X-Gly-Thr-Arg-Thr-Gln-Leu-Gln-Gly-Ala-Ser-Val-Thr-Y; Seq. ID No 9: X-Gly-Thr-Arg-Gln-Thr-Leu-Gln-Gly-Ala-Ser-Val-Thr-Y; Seq. ID No 10: X-Pro-Ala-Asn-Val-Val-Gly-Thr-Arg-Thr-Gln-Leu-Gln-Gly-Y; Seq. ID No 11: X-Pro-Ala-Asn-Val-Val-Gly-Thr-Arg-Gln-Thr-Leu-Gln-Gly-Y; Seq. ID No 12: X-Thr-Gly-Gln-Gly-Asn-Ser-Leu-Lys-Val-Gly-Asn-Ala-Asp-Y; Seq. ID No 13: X-Ala-Thr-Val-Tyr-Met-Ile-Asp-Ser-Val-Leu-Met-Pro-Pro-Ala-Y; and Seq. ID No 14: X-Pro-Gln-Val-Asn-Leu-Val-Asp-Thr-Leu-Asn-His-Gly-Gln-Tyr-Ser-Y; wherein X and Y may each independently be absent or independently be one or more amino acid residues, with the proviso that when present they do not provide or form part of an epitope of the MPB-70 protein of at least one strain of (Mycobacterium bovis) which is contiguous with the sequence to which X and Y are attached, X or Y optionally being terminated by a functionalised coupling moiety. The synthetic polypeptides according to the invention may be used to elicit the production of antibodies to the MPB-70 protein.
