  • Patent number: 6020180
    Abstract: A DNA sequence encoding a lipase having the amino acid sequence shown in SEQ ID NO:2. The lipase has a trypsin-like catalytic triad including an active serine located in a predominantly hydrophobic, elongated binding pocket of the lipase molecule and, located in a critical position of a lipid contact zone of the lipase structure, an amino acid residue different from an aromatic amino acid residue, which amino acid residue interacts with a lipid substrate at or during hydrolysis, in which lipase variant of the amino acid residue has been replaced by an aromatic amino acid residue so as to confer to the variant an increased specific activity as compared to that of the parent lipase.

  • Patent number: 5914306
    Abstract: This invention relates to novel stabilized enzymes. More specifically the invention relates to novel stabilized enzymes, in which a naturally occurring amino acid residue (other than proline) has been substituted with a proline residue at one or more positions; at which position(s) the dihedral angles .phi. (phi) constitute values within the interval ?-90.degree.<.phi.<-40.degree.!; preferably the dihedral angles .phi. (phi) and .psi. (psi) constitute values within the intervals ?-90.degree.<.psi.<-40.degree.! and ?-180.degree.<.psi.<-150.degree. or -80<$g c)<10 or 100<.psi.<180!; and which positions(s) is/are not located in regions in which the enzyme is characterized by possessing .alpha.-helical or .beta.-sheet structure. The invention also relates to nucleotide sequences encoding the novel stabilized enzymes, and expression vectors and host organisms containing the nucleotide sequences.
