Part:BBa_K817018
gamma-delta resolvase cassette
This cassette encodes an autoregulated resolvase(serine type recombinase)from E.coli F plasmid transposon tn1000(tn3 family). Its promoter region consists of 3 sub-sites(res site) and can process recombination. This cassette can resolve multimer that formed during replicative transposition, so it can also resolve plasmid multimer providing plasmid stability by avoiding dimer catastrophe. For this reason, it is multimer resolution system(MRS) that provide the same function as E.coli chromosome XerCD/dif but acts independent of cell cycle and may have higher efficiency on plasmids compared with slow XerCD system.

Functional Parameters: Austin_UTexas
Burden Imposed by this Part:
Burden is the percent reduction in the growth rate of E. coli cells transformed with a plasmid containing this BioBrick (± values are 95% confidence limits). This BioBrick did not exhibit a burden that was significantly greater than zero (i.e., it appears to have little to no impact on growth). Therefore, users can depend on this part to remain stable for many bacterial cell divisions and in large culture volumes. Refer to any one of the BBa_K3174002 - BBa_K3174007 pages for more information on the methods, an explanation of the sources of burden, and other conclusions from a large-scale measurement project conducted by the 2019 Austin_UTexas team.
This functional parameter was added by the 2020 Austin_UTexas team.
