Part:BBa_K539119
crtY (lycopene cyclase)
This is the coding sequence of crtY from Pantoea ananatis (formerly Erwinia uredovora) (Accession number D90087). It encodes lycopene B-cyclase, part of the carotenoid biosynthesis pathway, which converts lycopene to B-carotene (Misawa, N., Nakagawa, N., Kobayashi, K., Yamano, S., Nakamura, K., and Harashima, K. 1990. Elucidation of the Erwinia uredovora carotenoid biosynthetic pathway by functional analysis of gene products expressed in Escherichia coli. Journal of Bacteriology 172, 6704-612).
We found a point mutation of [BBa_K118008] [1](iGEM08_Edinburgh) at SpeI site that mutate into ACCTAGT. However, We corrected it successfully(ACCTAGT->ACTAGT), and submited to igem.
The following is the gel electrophoresis result of crtY Part:BBa_K118008. The sample included are uncut plasmid, cut by EcoR1, Xba1, Spe1 and Pst1 respctivly.
We can see that the location of plasmid cut by Spe1 is the same as uncut plasmid. We assumed that Spe1 site has mutated.
After the Point Mutation, we correct the Spe1 site and the gel electrophoresis result is shown below.

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.
