Week 3 - Development

Primer Design
Primers were designed to convert MelA into a biobrick. Primers A and F are for either end (including prefix and suffix - highlighted in green). The other primers surround the unwanted restiction sites (highlighted in yellow) with the changed base in red.
These correspond to the parts on the gene shown below. The stars correspond to the two unwanted restriction sites.
Orange Pigment
Used plasmid editor to examine the genes used for the production of orange pigments. The (supposedly) orange-producing pigment from the biobricks:
We also tried a preliminary design for a biobrick we could construct, in case the orange biobrick does not function. This uses the same genetic synthetic pathway for gene consruction:
Transformed Pigments
The MelA plate left on the bench overnight produced a brown-coloured pigment! Growth on media containing IPTG should produce this pigment a lot faster.
Amplification system
- Activators
- Found parts submitted by Cambridge '07 team amplifier project. Three translational units (ribosome binding sites and protein coding sequence) for the three activators. Sequence below.

- Promoters
Available as individual parts, with a GFP reporter or as part of a composite with the activator upstream. Five promoters as used by Cambridge '07:
PF promoter, part: I746360 PO promoter, part: I746361 PP promoter, part: I746362 Psid promoter, part: I746364 PLL promoter, part: I746365
- Degradation Tags
- three tags are well described in Andersen, J. B., Sternberg, C., Poulsen, L. K., Bjorn, S. P., Givskov, M. & Molin, S. (1998). New unstable variants of green fluorescent protein for studies of transient gene expression in bacteria. Appl Environ Microbiol 64, 2240–2246.[http://aem.asm.org/cgi/reprint/64/6/2240], which detailed tagged-GFP degredation.
- the tags as described in the paper that we could use are as follows:
