Summary
This study presents a simple protocol for engineering synthetic baculovirus genomes using Red/ET homologous recombination. This method enhances protein production by enabling tailored baculovirus expression vector systems (BEVS) for specific applications.
Area of Science:
- Molecular Biology
- Biotechnology
- Genomics
Background:
- Baculovirus expression vector systems (BEVS) are established tools for heterologous protein production.
- BEVS have evolved over 30 years with modifications to enhance usability and protein yield.
- Recent advances in synthetic DNA synthesis allow for engineering of entire or partial baculovirus genomes.
Purpose of the Study:
- To describe a straightforward protocol for constructing modified baculovirus genomes.
- To utilize synthetic DNA segments for redesigning BEVS.
- To leverage Red/ET homologous recombination for genome engineering.
Main Methods:
- Utilized iterative Red/ET homologous recombination reactions.

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
