Abstract: A new I-CreI derived single-chain meganuclease comprising two domains, each domain comprising a portion of a parent I-CreI monomer which extends at least from the beginning of the first alpha helix to the end of the C-terminal loop and said two domains being joined by a peptidic linker which allows them to fold as a I-CreI dimer that is able to bind and cleave a chimeric DNA target comprising one different half of each parent homodimeric I-CreI meganuclease target sequence. Use of said I-CreI derived single-chain meganuclease for genetic engineering, genome therapy and antiviral therapy.
Abstract: A thermostable mutant DNA polymerase; a method for obtaining the thernmostable mutant DNA polymerase by identifying a thermostable mutant polypeptide exhibiting enzymatic activity, wherein the thermostable mutant polypeptide is a variant of DNA polymerase I obtained from Thermus aquaticus; a polynucleotide, an expression vector, and a host cell encoding the thermostable mutant DNA polymerase; and a method of performing a reverse transcription polymerase chain reaction (RT-PCR) utilizing the thermostable mutant DNA polymerase, as well as a kit for facilitating the same.
