Latest Patents

One of Takatsu's latest patents is a heat-resistant reverse transcriptase mutant. This invention includes a reverse transcriptase mutant characterized by an amino acid mutation at a specific position in the amino acid sequence of wild-type reverse transcriptase derived from the Moloney murine leukemia virus. The mutation involves a substitution from threonine to another amino acid, selected from a group of nonpolar aliphatic side chains and polar acidic functional groups. This patent also encompasses a nucleic acid encoding the mutant, methods for producing the mutant and the nucleic acid, and a composition and kit that include the mutant.

Another notable patent is for a DNA polymerase variant, specifically a Taq polymerase with enhanced strand displacement activity. This invention involves substituting an amino acid residue in the template DNA binding site to increase the total charge in that site. The patent details a nucleic acid encoding the polymerase, a vector containing the nucleic acid, and methods for amplifying nucleic acids using this polymerase. The resulting DNA polymerase is characterized by high thermostability and efficiency in replicating long strands of template DNA.
