Abstract: Stabilized reverse transcriptase fusion proteins including a thermostable reverse transcriptase connected to a stabilizer protein are described. Attaching the stabilizer protein to the thermostable reverse transcriptase stabilizes the fusion protein and can aid in its purification, provide increased solubility, allow for longer storage, or allow the fusion protein to be used under more rigorous conditions such as higher temperature. The stabilized reverse transcriptase fusion protein can also include a linker between the stabilizer protein and the thermostable reverse temperature. The stabilized reverse transcriptase fusion proteins are suitable for use in nucleic acid amplification methods such as the reverse transcription polymerase chain reaction and other applications involving cDNA synthesis.

Abstract: Provided herein are systems and methods for nucleotide incorporation reactions. The systems comprise polymerases having altered nucleotide incorporation kinetics and are linked to an energy transfer donor moiety, and nucleotide molecules linked with at least one energy transfer acceptor moiety. The donor and acceptor moieties undergo energy transfer when the polymerase and nucleotide are proximal to each other during nucleotide binding and/or nucleotide incorporation. As the donor and acceptor moieties undergo energy transfer, they generate an energy transfer signal which can be associated with nucleotide binding or incorporation. Detecting a time sequence of the generated signals, or the change in the signals, can be used to determine the order of the incorporated nucleotides, and can therefore be used to deduce the sequence of the target molecule.

Abstract: This invention provides for an improved generation of novel nucleic acid modifying enzymes. The improvement is the fusion of a sequence-non-specific nucleic-acid-binding domain to the enzyme in a manner that enhances the ability of the enzyme to bind and catalytically modify the nucleic acid.
Abstract: Modified DNA polymerases have an affinity for DNA such that the polymerase has an ability to incorporate one or more nucleotides into a plurality of separate DNA templates in each reaction cycle. The polymerases are capable of forming an increased number of productive polymerase-DNA complexes in each reaction cycle. The modified polymerases may be used in a number of DNA sequencing applications, especially in the context of clustered arrays.

Abstract: An object is to identify endoglucanase and ?-glucosidase genes by isolating genomic DNA containing cellulase genes, which are classified into endoglucanases or ?-glucosidases, from Acremonium cellulolyticus, and sequencing the nucleotide sequences thereof. The inventors intensively compared the amino acid sequences of known endoglucanases and ?-glucosidases with each other to find conserved region of amino acid sequences in Acremonium cellulolyticus, and various primers were designed based on the information. PCR was carried out using the various primers thus designed and genomic DNA or cDNA as a template. As a result, gene fragments of endoglucanases and ?-glucosidases were obtained. Primers were designed based on the gene fragments, and PCR was carried out to amplify nine genes of endoglucanases and ?-glucosidases. The nucleotide sequences thereof were sequenced, and the present invention was completed.
Abstract: A DNA polymerase, having an amino acid sequence represented by SEQ ID No. 2, or a derivative of the amino acid sequence by substitution, deletion, or addition of at least one amino acid residue. The DNA polymerase is a hybrid DNA polymerase prepared by inserting a thioredoxin binding domain (TBD) of bacteriophage T7 DNA polymerase into a DNA polymerase I (Sau) of Staphylococcus aureus. A method for preparing the DNA polymerase includes: 1) determining a corresponding position and a target substitution sequence in Sau protein for the TBD of the bacteriophage T7 DNA polymerase; 2) devising and synthesizing a primer according to a gene sequence of Sau and a sequence TBD published by GenBank; 3) cloning the Sau-TBD segment acquired in (2) to an expression vector pTrc99A to construct a recombinant vector pTrc99A-Sau-TBD; and 4) transforming Escherichia coli by the recombinant vector pTrc99A-Sau-TBD and inducing protein expression.
