The present invention is directed to variant polypeptides having enhanced ketoreductase activity and/or thermostability for use in the stereospecific reduction of ketones. In addition, the present invention is directed to polynucleotides that encode the ketoreductase polypeptides, including codon optimized versions of the polynucleotides which provide for enhanced expression in host cells. In another aspect, the present invention is directed to nucleotide constructs, vectors and host cells that are transformed with polynucleotides of the present invention.
摘要:
The invention relates to a fed-batch fermentation process which uses special E. coli host/vector systems for the purpose of efficiently forming recombinant proteins, in particular recombinant antibody molecules, preferably antibody fragments such as miniantibodies. Under the given conditions, the E. coli cells are able to grow at a maximum specific growth rate up to very high cell densities. After the recombinant product formation has been switched on, it is only the formed product which restricts growth; there is no growth restriction due to substrates or metabolic by-products. High space-time yields of recombinant proteins can be achieved in this manner.

The present invention is directed to glucose dehydrogenase (GDH) polypeptides that have enhanced GDH activity and/or thermostability relative to the backbone wild-type glucose dehydrogenase polypeptide. In addition, the present invention is directed to a polynucleotide that encodes for the GDH polypeptides of the present invention, to nucleic acid sequences comprising the polynucleotides, to expression vectors comprising the polynucleotides operatively linked to a promoter, to host cells transformed to express the GDH polypeptides, and to a method for producing the GDH polypeptides of the present invention.
