Patent ID: 8916681

Claim:
A peptide molecule comprising the sequence: X 1 -G/W- X 2 -R/(D)R- X 3 (SEQ ID NO: 3) wherein: X 1 is F or A or any D-amino-acid residue; X 2 is L or A or any D-amino-acid residue; X 3 is F or W; wherein the C-terminal amino acid residue of the peptide molecule contains group z which removes the charge on that residue; and, wherein the peptide molecule further comprises the sequence: R-R-M-K-W-K-K-Y (SEQ ID NO: 20) at the N-terminus; and further wherein the peptide sequence is not: F-G-L-R-F; (SEQ ID NO: 4) F-G-L-R-W; (SEQ ID NO: 5) F-G-(D)F-R-F; (SEQ ID NO: 6) F-G-A-R-W; (SEQ ID NO: 7) F-G-L-(D)R-W; (SEQ ID NO: 8) F-G-(D)L-R-W; (SEQ ID NO: 9) A-G-L-R-W; (SEQ ID NO: 17) or (D)F-G-L-R-W (SEQ ID NO: 10).
