The present disclosure also relates to the use of the compositions comprising the recombinant factor VIII polypeptides or polynucleotides encoding the recombinant factor VIII polypeptides for therapeutic purposes.

Abstract: The present disclosure provides engineered oxalate decarboxylase (ODC) polypeptides and compositions thereof, as well as polynucleotides encoding the engineered oxalate decarboxylase polypeptides. The present disclosure also provides methods of using the engineered enzymes and compositions thereof for treating diseases or conditions associated with abnormal metabolism of oxalate.

Abstract: The present invention provides engineered leucine decarboxylase (LDC) polypeptides and compositions thereof, as well as polynucleotides encoding the engineered leucine decarboxylase polypeptides. In some embodiments, the engineered leucine decarboxylase polypeptides display enhanced catalytic activity, as well as reduced sensitivity to proteolysis, and/or increased tolerance to low pH environments. In some embodiments, the engineered leucine decarboxylase polypeptides are optimized to provide improved storage stability. The present invention also provides methods for the use of the compositions comprising the engineered leucine decarboxylase polypeptides for therapeutic and industrial purposes.

Abstract: The present disclosure relates to engineered DNA polymerase polypeptides and compositions thereof, as well as polynucleotides encoding the engineered DNA polymerase polypeptides. The present disclosure also provides methods of using the engineered DNA polymerase polypeptides or compositions thereof for diagnostic and other purposes.

Abstract: The present invention provides engineered methionine gamma lyase polypeptides and compositions thereof. The engineered methionine gamma lyase polypeptides have been optimized to provide improved thermostability, protease stability, and stability under a range of pH conditions, including acidic (pH<7) conditions. The present invention also relates to the use of the compositions comprising the engineered methionine gamma lyase polypeptides for therapeutic purposes.
