  • Patent number: 11739310
    Abstract: An amino acid sequence may have at least 70% sequence identity to the amino acid sequence identified in SEQ ID No. 1 over its entire length, and (a) an amino acid substitution on the position corresponding to the position 271, and (b1) at least one other amino acid substitution for at least one of the positions corresponding to the positions 18, 61, 92, 99, 137, 149, 156, 159, 162, 166, 172, 192, 199, 217, 265, or combinations thereof; and/or (b2) an amino acid substitution on the position corresponding to the position 9, and another amino acid substitution for at least one position corresponding to the positions 29, 48, 101, 130, 31, 133, 144, 217, 224, 252, or combinations thereof.
