Variants of the bacteriophage B103 DNA polymerase are described herein. The variant has improved properties, that include when compared to wild-type Phi29 DNA polymerase, at least one of the following: increased thermostability, improved reaction rate for DNA amplification, reduced background and a reduction of bias. Methods of using the DNA polymerase variant are also described herein.

The present disclosure provides compositions and methods for performance of targeted mutagenesis in higher eukaryotic cells, e.g., mammalian cells, across large stretches of targeted sequence. Compositions and methods that rely upon combination of a bacteriophage polymerase with a nucleic acid-editing deaminase to achieve robust mutagenesis of targeted regions of nucleic acid sequence under control of a phage promoter are specifically provided.

The invention relates to novel variants and mutants of HK022 bacteriophage integrase (HK-Int), systems, kits, compositions, methods and uses thereof for gene therapy using site-specific recombination. More specifically, the invention further provides donor cassettes comprising replacement sequences for targeted replacement of target nucleic acid sequences using the HK-Int variants of the invention.

The present invention concerns a method for expressing a recombinant DNA molecule in a eukaryotic host cell, comprising the steps of: (a) expressing or introducing at least one chimeric protein, in said host cell, wherein said chimeric protein comprises: (i) at least one catalytic domain of a capping enzyme, in particular selected in the group consisting of cap-0 canonical capping enzymes, cap-0 non-canonical capping enzymes, cap-1 capping enzymes and cap-2 capping enzymes; and (ii) at least one catalytic domain of a DNA-dependent RNA polymerase, in particular a bacteriophage DNA-dependent RNA polymerase, (b) constitutively or transiently downregulating the phosphorylation level of subunit a of translation initiation factor eIF2 (eIF2α) in said host cell.

The invention also concerns an isolated nucleic acid molecule or a set of nucleic acid molecules, comprising or consisting of (1) at least one nucleic acid sequence encoding a chimeric protein comprising at least one catalytic domain of a capping enzyme; and at least one catalytic domain of a DNA-dependent RNA polymerase; and (2) at least one nucleic acid sequence downregulating the phosphorylation level of eIF2α in a eukaryotic host cell or encoding a polypeptide downregulating said phosphorylation level; and (3) optionally, at least one nucleic acid sequence encoding a poly(A) polymerase, as well as vectors, kits and cells comprising said nucleic acid molecule or set, and different uses and applications thereof.

The present disclosure relates generally to bacterial delivery vehicles for use in efficient transfer of a desired payload into a target bacterial cell. More specifically, the present disclosure relates to bacterial delivery vehicles with desired host ranges based on the presence of a chimeric receptor binding protein (RBP) composed of a fusion between the N-terminal region of a RBP derived from a lambda-like bacteriophage and the C-terminal region of a different RBP.

The invention relates to the field of microbiology, specifically to a bacteriophage or a combination of bacteriophages, to a composition comprising said bacteriophage or comprising said combination of bacteriophages for preventing, treating or controlling contamination with and/or growth of Listeria, including Listeria monocytogenes and Listeria serovar (SV) 1/2 mutants that are resistant to bacteriophage P100 and/or Listeria serovar 3. The invention further relates to the a method for controlling contamination with Listeria, including Listeria monocytogenes and Listeria serovar (SV) 1/2 mutants that are resistant to bacteriophage P100 and/or Listeria serovar 3, in a food product, on food processing equipment, or on food storage containers by applying the bacteriophage or the combination of bacteriophages, to the composition comprising said bacteriophage or said combination of bacteriophages to a food product or food processing equipment to reduce the amount of Listeria.

The invention relates to systems, methods, and compositions for the genetic modification of Wolbachia.

A novel Acinetobacter baumannii bacteriophage and lytic protein derived from the bacteriophage are disclosed. The bacteriophage and lytic protein derived from the bacteriophage both have strong in vitro antibacterial effects on pan-drug resistant Acinetobacter baumannii clinical strains providing experimental basis for developing a preparation for preventing and treating infections caused by Acinetobacter baumannii containing the bacteriophage or lytic protein thereof.
