Utilization of Site-Specific Recombination in Biopharmaceutical Production
Mammalian expression systems, due to their capacity in post-translational modification, are preferred systems for biopharmaceutical protein production. Several recombinant protein systems have been introduced to the market, most of which are under clinical development. In spite of significant improvements such as cell line engineering, introducing novel expression methods, gene silencing and pr...
متن کاملTnpI recombinase: identification of sites within Tn5401 required for TnpI binding and site-specific recombination.
The Bacillus thuringiensis class II transposon Tn5401 encodes a recombinase protein, TnpI, that mediates the resolution of cointegrate molecules generated as intermediates during Tn5401 transposition by the TnpA transposase. This recombination event requires a specific target site, or internal resolution site, at which TnpI binds and catalyzes the exchange of DNA strands. Gel mobility shift ass...
متن کاملFLP Recombinase-Mediated Site-Specific Recombination in Silkworm, Bombyx mori
A comprehensive understanding of gene function and the production of site-specific genetically modified mutants are two major goals of genetic engineering in the post-genomic era. Although site-specific recombination systems have been powerful tools for genome manipulation of many organisms, they have not yet been established for use in the manipulation of the silkworm Bombyx mori genome. In th...
متن کاملXer Site Specific Recombination: Double and Single Recombinase Systems
The separation and segregation of newly replicated bacterial chromosomes can be constrained by the formation of circular chromosome dimers caused by crossing over during homologous recombination events. In Escherichia coli and most bacteria, dimers are resolved to monomers by site-specific recombination, a process performed by two Chromosomally Encoded tyrosine Recombinases (XerC and XerD). Xer...
متن کاملIntermediates in serine recombinase-mediated site-specific recombination.
Site-specific recombinases are enzymes that promote precise rearrangements of DNA sequences. They do this by cutting and rejoining the DNA strands at specific positions within a pair of target sites recognized and bound by the recombinase. One group of these enzymes, the serine recombinases, initiates strand exchange by making double-strand breaks in the DNA of the two sites, in an intermediate...
