  "abstract": "A recombinant protein with D-hydantoinase activity which has the amino acid sequence SEQ ID NO 1 is obtainable in large amounts and has an improved temperature stability.",
  "claims": [
    "1. Isolated nucleic acid molecule which codes for a protein consisting of the amino acid sequence set forth in SEQ ID NO: 1, wherein said protein has D-hydantoinase activity, and retains about 100% of said D-hydantoinase activity after 20 minutes at 60° C., when present in a 50 mmol/l Tris buffer, pH 7.8, at a concentration of 15 mg/ml, and retains about 80% of said D-hydantoinase activity after 20 minutes at 65° C., in a 50 mmol/l Tris buffer at pH 7.8.",
    "2. The isolated nucleic acid molecule of claim 1, selected from the group consisting of: (i) an isolated nucleic acid molecule having the nucleotide sequence of SEQ ID NO: 2, and (ii) an isolated nucleic acid molecule complementary to SEQ ID NO: 2.",
    "3. Recombinant vector comprising the isolated nucleic acid molecule of claim 1, operably linked to a promoter.",
    "4. Isolated host cell transformed or transfected with the isolated nucleic acid molecule of claim 1.",
    "5. The isolated host cell of claim 4, wherein said cell is prokaryotic.",
    "6. The isolated host cell of claim 4, wherein said cell is eukaryotic.",
    "7. The isolated host cell of claim 5, wherein said cell is E. coli.",
    "8. The isolated host cell of claim 6, wherein said cell is Saccharomyces."
