recombinase

(rē-kŏm′bə-nās′, -nāz′)
n.
An enzyme that catalyzes the exchange of short pieces of DNA between two long DNA strands, particularly the exchange of homologous regions between the paired maternal and paternal chromosomes.

recombinase

(rē-kŏm′bĭn-ās) [ recombinan(t) + ″]
Any enzyme that catalyzes nucleic acid recombination, i.e., the rearrangement of genetic material on a strand of DNA or RNA.

recombinase

a function of the recA protein in Escherichia coli that catalyzes the binding and unwinding of the double strands of DNA that form a synapse during DNA recombination.

Site-specific inversion require the presence of specific recombinase enzymes which invert particular DNA fragment resulting in ON to OFF or OFF to ON switching of gene placed within the invertable segment of DNA or next to the switch.
However, for medical or environmental applications, the recombinases could be re-engineered to respond to other conditions such as acidity or the presence of specific transcription factors (proteins that control gene expression).
cholerae genome depends on two host encoded tyrosine recombinases, XerC and XerD (18).
Phase variation of the 987P-like CS18 fimbriae of human enterotoxigenic Escherichia coli is regulated by site specific recombinases.
In jawed vertebrates these recombinases mediate the rearrangement process.
An appropriate combination of these recombinases would improve the overall ability to characterize a gene function more precisely (Raymond and Soriano, 2007).
Cozzarelli elucidated the nature of DNA architecture and growth through enzymologic studies of polymerases, ligases, recombinases, and topoisomerases.
These include restriction endonucleases for cleaving DNA and ligases for joining the fragments, recombinases that can execute a large variety of DNA cleavage and joining reactions.
We use the wild type strain WFD11 and its derivative, DS52, which lacks the radA gene, an archaeal member of the recA/RAD51 family of recombinases.
Not only are the constructs more complicated and hence more unstable and prone to horizontal gene transfer, the gene products used are cell poisons or recombinases, ie, genome scramblers.
They used a class of proteins known as recombinases, which can record information into bacterial DNA by recognizing specific DNA addresses and inverting their direction.
