Part:BBa_K118000

dxs coding sequence encoding 1-deoxyxylulose-5-phosphate synthase

This is the coding sequence of dxs from Escherichia coli JM109. It encodes 1-deoxyxylulose-5-phosphate synthase, thiamine-requiring, which catalyses the first step in the biosynthesis of terpenoids. Overexpression of dxs has been reported to increase yields of carotenoids and other terpenoids (Kang, M.J., Lee, Y.M., Yoon, S.H., Kim, J.H., Ock, S.W., Jung, K.H., Shin, Y.C., Keasling, J.D., and Kim, S.W. 2005. Identification of genes affecting lycopene accumulation in Escherichia coli using a shot-gun method. Biotechnology and Bioengineering 91, 636-642).

BBa_K118000 parameters

Burden Imposed by this Part:

Burden Value: 4.3 ± 4.6%

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.
