Strong constitutive promoter
During our project we have chosen 2 biobrick promoters (J23100 and J23106) and modified them to be suitable for direct cloning. Such approach allows for amplification of the modified promoter without the need to carry out more cloning steps and modifications. We designed our biobricks to compose of a working medium or strong promoter followed by a ribosomal binding site designed for E. coli strains. With such design, anyone using our biobrick will be able to clone their construct directly in front of a desired gene and express their protein. Our biobricks were cloned into pSB1C3 plasmids as shown below. Due to difficulties with cloning, only the strong promoter was submitted to the registry (BBa_K2016000)

McHr - hemerythrin
McHr is a protein expressed by methane-oxidising bacterium: Methylococcus capsulatus. The family of hemerythrins can undergo a slow process of oxygenation upon binding of iron which causes their colour change from colourless into red/yellow. Its mechanism of oxygenation has been discovered to be much more rapid than other hemerythrins we investigated (DcrHr or TdHr). This gene was synthesised based on the GeneBank sequence entry and cloned into the pSB1C3 plasmid.

Biobrick is cloned between XbaI and SpeI sites, however it is cloned in reverse orientation due to XbaI and SpeI enzymes having the same overhangs after restriction digest. To use this biobrick future teams should use PCR apmlification rather than restriction digest to clone this biobrick.
