COMPOSITE PARTS
All of our gold, silver and bronze winning parts are composite parts, consisting of a multitude of basic parts
The complete sequences and characteristics of these basic parts are linked on the Parts Registry pages of our composite parts which are linked in each table.
Best Composite Part
Our best basic part is our Winsulin BBa_K2417007">(BBa_K2417007) as this part is designed by us (with the help of Peter Arvan and his laboratory) and is also open-source. This part is a single chain insulin which means that there is no extra processing step that must occur to make it functional such as the need to cleave the c peptide in proinsulin to make it functional insulin. This simplifies the production of this insulin. Single-chained insulins are also considered to have greater stability compared to human insulin and other analogues and would therefore be preferable.

Novel short chain insulin
analogue (Winsulin) with a 12AA linker YncM secretion tag to
translocate protein into media N-terminal 6x His Tag
purification 4x GSS flexible linker TEV protease cleavage site Extended ribosome binding site |
We
demonstrated that it works: · We tested it in
insulin-sensitive cell lines and saw an increase in glycogen synthesis and
glucose oxidation above basal levels, proving its bioactivity · We showed via an
ELISA assay that whilst the cell lysate did not contain Winsulin,
the media in which the cells were growing did. Therefore
the YncM secretion tag worked as expected The
results for these assays can be found here |
|
|
|
Human proinsulin N-terminal Ecotin
tag for targeting proteins to the periplasm N-terminal 6x His tag 4x GGS flexible linker Trypsin protease cleavage site
for His-tag and C-peptide cleavage Extended ribosomal binding
site |
We
improved previous parts: BBa_M39904 and BBa_M1877 by: Completing their sequence Adding a periplasmic
transporter tag (for more efficient folding in an oxidative environment) Adding an efficient ribosomal binding
site Adding an N-terminal His tag
for purification We
demonstrated that it works: · By testing it
insulin-sensitive cell lines and saw an increase in glycogen synthesis and
glucose oxidation above basal levels, therefore proving its bioactivity The
results for these assays can be found here |

Cytoplasmic-Winsulin |
|
Novel single chain insulin
analogue (Winsulin) with a 12AA linker (QRGGGSGGGQRR) N-terminal 6x His Tag 4x GSS flexible linker TEV protease cleavage site Extended ribosome binding site |
· We validated our
parts by showing that they work in producing insulin. We performed an ELISA
assay testing for properly folded insulin, and detected the presence of
Cytoplasmic Winsulin. The
results for the assay can be found here |

Ecotin-Winsulin |
|
Novel single chain insulin
analogue (Winsulin) with a 12AA linker (QRGGGSGGGQRR) N-terminal Ecotin
tag for targeting proteins to the periplasm N-terminal 6x His Tag 4x GSS flexible linker TEV protease cleavage site Extended ribosome binding site |
We submitted this DNA part to
the registry, for other teams to use in the future |
