Patent ID: 8618251

Claim:
An amino acid sequence comprising a first fragment consisting of amino acids 215-396 of SEQ ID NO: 1, wherein in said fragment, amino acids corresponding to amino acids at positions 215, 326, 359, and 396 of SEQ ID NO: 1 are different from said amino acids present in SEQ ID NO: 1, or a second fragment consisting of amino acids 247-354 of SEQ ID NO: 1, wherein in said fragment, amino acids corresponding to amino acids at positions 247, 252, 266, 278, 302, and 354 of SEQ ID NO: 1 are different from said amino acids present in SEQ ID NO: 1, or a third fragment consisting of amino acids 211-399 of SEQ ID NO: 1, wherein in said fragment, amino acids corresponding to amino acids at positions 211, 243, 326, and 399 of SEQ ID NO: 1 are different from said amino acids present in SEQ ID NO: 1, or a fourth fragment consisting of amino acids 210-378 of SEQ ID NO: 1, wherein in said fragment, amino acids corresponding to amino acids at positions 210, 285, 326, 369, and 378 of SEQ ID NO: 1 are different from said amino acids present in SEQ ID NO: 1.
