Abstract: The present disclosure provides recombinant factor VIII polypeptides, polynucleotides encoding the recombinant factor VIII polypeptides, and compositions thereof, wherein the recombinant factor VIII polypeptides have been engineered to provide improved expression, activity/potency, clotting activity/potency, serum/plasma stability, and/or reduced immunogenicity. 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 enone reductase enzymes (EREDs), polypeptides having ERED activity, and polynucleotides encoding these enzymes, as well as vectors and host cells comprising these polynucleotides and polypeptides. Methods for producing ERED enzymes are also provided. The present disclosure also provides engineered ketoreductase enzymes (KREDs), polypeptides having KRED activity, and polynucleotides encoding these enzymes, as well as vectors and host cells comprising these polynucleotides and polypeptides. Methods for producing KRED enzymes are also provided. The present disclosure further provides compositions comprising the ERED and KRED enzymes and methods of using the engineered ERED and KRED enzymes. The present disclosure finds particular use in the production of pharmaceutical compounds.

Abstract: The present invention provides mucin-binding fusion proteins suitable for extending the residence time of oral therapeutics in the intestinal tract.
