    摘要: The present invention provides engineered branched chain ketoacid decarboxylase (KdcA) polypeptides and compositions thereof, as well as polynucleotides encoding the engineered branched chain ketoacid decarboxylase (KdcA) polypeptides. In some embodiments, the engineered KdcA polypeptides are optimized to provide enhanced catalytic activity, as well as reduced sensitivity to proteolysis and increased tolerance to storage at elevated temperatures. The present invention also provides methods for the use of the compositions comprising the engineered KdcA polypeptides for therapeutic and industrial purposes.

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