Secondly, we had the Ribosome Binding site which signals the start of translation from mRNA to protein. | Secondly, we had the Ribosome Binding site which signals the start of translation from mRNA to protein. | ||

+ | During the first year of our project, the design of our constructs was a bit lacking. This year, we made improvements to our biobricks that would allow them to function better. To make sure the two enzymes the bacteria produced would be able to exit the cell, we added a PelB periplasmic secretion tag. Once the enzymes were secreted to the periplasm, they would be able to exit the cell on their own. | ||

+ | To allow us to easily isolate the enzymes once they were produced, we added a his tag to our constructs. This would allow us to purify our enzymes on a nickel column before running them on a protein gel. These design changes would contribute to the success of our project by allowing the enzymes to be secreted from the cell and allowing us to easily test for enzyme production. | ||

BALTIMORE BIO-CREW
Bio-Engineering E.Coli To Degrade Plastic and Save The Baltimore Inner Harbor
Design
- catalyzes PET hydrolysis
- Turns PET into MHET (Mono (2-hydroxyethyl) Terephthalate acid)
- Breaks down MHET
- Turns MHET into ethylene glycol and terephthalic acid.
