  • Microorganism for producing recombinant pig liver esterase
    Patent number: 8017354
    Abstract: The present invention relates to a microorganism which comprises at least one copy of a polynucleic acid sequence which is foreign to the host and which encodes a protein having an enzymic activity, and comprises a chaperone system which assists the expression of the protein in the form of an active enzyme, and to a method for producing a protein having esterase activity using such a microorganism.

  • PROCESS FOR PREPARING ENANTIOMERICALLY ENRICHED AMINES
    Publication number: 20090117627
    Abstract: A process for preparing enantiomerically enriched amines by reacting a ketone with ammonia or an ammonium salt and a reducing agent in the presence of a catalytic system comprising the components: a) an amino acid transaminase, b) an alpha-amino acid which is a substrate of the amino acid transaminase, c) an amino acid dehydrogenase suitable for preparing the alpha-amino acid, d) NAD(P)+ and e) an NAD(P)+-reducing enzyme, which reacts NAD(P)+ with the reducing agent to give NAD(P)H. The process can be carried out with catalytic amounts of alpha-amino acid and NAD(P)+, and enables an enantioselective reductive amination of ketones.
