  • Group of novel enantioselective microbial nitrile hydratases with broad substrate specificity
    Patent number: 8470576
    Abstract: The present invention provides a polynucleotide or a pair of polynucleotides encoding an enzyme having nitrile hydratase (NHase) [E.C. 4.2.1.84] activity. Furthermore, a vector and a host comprising the disclosed polynucleotide or pair of polynucleotides and methods for the production of the same are provided. Moreover, the invention relates to a pair of polypeptides or a fusion protein having NHase activity, an antibody specifically binding to the pair of polypeptides or fusion protein, a primer or probe, which specifically hybridizes under stringent conditions to the disclosed polynucleotide or either one of the pair of polynucleotides, a composition comprising the polynucleotide or pair of polynucleotides, the pair of polypeptides or fusion protein, the antibody and/or one or more primers or probes of the invention and a method for the production of amides comprising the enantioselective conversion of nitriles.

  • Reca-negative and rhab-negative microorganism
    Publication number: 20070128689
    Abstract: The present invention describes new microorganisms specifically for use as expression systems for rhamnose-in-ducible promoters. Due to the combination of rhamnose and recombination deficiency artificially created in these organisms, ex-pression systems which require less of the expensive rhamnose for induction and therefore can be induced more inexpensively, and have a higher genetic stability are obtained.
