Benzo[a]pyrene
✡ Introduction
(1)Why do we detect benzo[a]pyrene?
Because when food,such as fried food ,which is heated above 300 degrees
celcius,food will release benzo[a]pyrene recycled oil usually contain
benzo[a]pyrene[1].
(2)Harm?
Pathway:from skin,breathing in,eating Carcinogenic,environmental
pollution, Skin irritation,eye irritation[1].
(3)Taiwanese regulation
[2](4)National regulation
Europe:The same to Taiwanese regulation[2]
American:The MCL has been set at 0.2 ppb[3]
✡ Circuit Design
So far,we don’t find the protein which can combine with the Benzo[a]pyrene,so first
we must degradate it by Laccase. And its product is Bap-1,6-quinone which can
combine with the protein,in order that we can detect Benzo[a]pyrene. [4]
We put the gene fragment which can produce the Laccase in the E.coli
Let it produce itself.
QsrR is a protein which can combine with Bap-1,6-quinone.[5]As Laccase,we put the
gene fragment in the E.coli.Let it produce itself.
We design a gene part make QsrR repress sfRFP’s production.
Usually,QsrR is on the Binding Site,and red fluorescent protein will not be produced.
When QsrR combine with Bap-1,6-quinone, QsrR will be activated and go away.
And the transcription will carry on,then it will produce red fluorescent protein
