Part:BBa_K1218003

CRISPR CasA E. coli (Modern)

The E. coli CRISPR system uses the CASCADE complex to target invasive DNA. CasA is the first subunit of the CASCADE complex and is responsible for the initial identification of invasive DNA. This part can be used with casBCDE to create the full CASCADE protein complex.

BBa_K1218003 parameters

Burden Imposed by this Part:

Burden Value: 2.2 ± 5.1%

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.
