  • Patent number: 6468746
    Abstract: Proteins to be stabilized are incorporated between two domains of the gene III protein of a bacteriophage. A mixture of phages with a large repertoire of mutants of the protein to be stabilized in the gene III protein is treated with proteases. The phages which present the least stable variants of the protein lose their infectivity fastest, whereas those whose genes code for stabilized variants of the protein retain their infectivity longest. Infection of bacterial cells with the phages treated with proteases and multiplication thereof leads to enrichment of the phages which comprise genes of stabilized variants of the mutagenized protein. The sequences of the most stable variants of the protein are obtained in this way from the genomes of the phages remaining after several rounds of phage cultivation, proteolysis and reinfection.

  • Patent number: 6465223
    Abstract: The present invention relates to a process for resolving racemates of alkoxy-substituted primary amines by reacting with an ester in the presence of a lipase and subsequently separating the optically active amide which is formed from the unreacted optically active amine. This is followed where appropriate by hydrolysis of the optically active amide, separation of the optically active amine produced thereby from the acid from which the ester is derived, racemization and recycling of the unwanted enantiomer of the amine, and esterification and recycling of the acid.
