    Abstract: This invention relates to altered forms of members of the RNase A superfamily. An RNase A can be modified to be cytotoxic by altering its amino acid sequence so that it is not bound easily by the ribonuclease inhibitor while still retaining catalytic properties. While earlier work had identified some modifications to RNase A that would result in cytotoxicity, the use of the FADE algorithm for molecular interaction analysis has led to several other locations that were candidates for modification. Some of those modifications did result in RNase A variants with increase cytotoxicity.

    Abstract: The present invention provides materials and methods useful for error correction of nucleic acid molecules. In one embodiment of the invention, a first plurality of double-stranded nucleic acid molecules having a nucleotide mismatch are fragmented by exposure to a molecule having unidirectional mismatch endonuclease activity. The nucleic acid molecules are cut at the mismatch site or near the mismatch site, leaving a double-stranded nucleic acid molecule having a mismatch at the end or near end of the molecule. The nucleic acid molecule is then exposed to a molecule having unidirectional exonuclease activity to remove the mismatched nucleotide. The missing nucleotides can then be filled in by the action of, e.g., a molecule having DNA polymerase activity. The result is double-stranded nucleic acid molecules with a decreased frequency of nucleotide mismatches.

  • Publication number: 20130189760
    Abstract: The purpose of the present invention is to provide a nuclease that secretes natural nonpathogenic microorganisms extracellularly, has higher specific activity than conventional nucleases, and is useful in nucleolytic degradation on an industrial scale. This purpose is achieved with an extracellularly secreted nuclease derived from Streptomyces bacteria, the nuclease having specific activity equal to or greater than the specific activity of Benzonase® when supplied to double-stranded DNA for 30 minutes at 37° C. in 20 mM Tris/HCl (pH 8.5) containing 1 mM MgCl2 and 1 mM CaCl2 after purification, using double-stranded DNA, single-stranded DNA, and RNA as substrates.
