Introduction
This composite part contains constitutive promoter, RBS, mRFP, and two functional domains of Ubx protein. More detail about its crosslinking function is shown below.
Design
We designed mRFP(Part:E1010) as the functional protein between the two peptide regions(Part:K4377001 and Part:K4377002), in an attempt to verify the feasibility of self-assembling. ( result in Figure 1.) We choose mRFP as functional protein for testing because mRFP is easy to observe and check protein’s function.In order to purify our protein after expression, we added 10x His tag at the N terminal of Ubx protein. The reason we add 10x His tag at N terminal but not C terminal is to amplify the production of Ubx protein. To improve performance, we performed codon harmonization. The optimized sequence of codons will be more suitable for expression by our engineered E.coli .
Build
Cloning result
With the same process of building Composite part K4377006, we successfully built Composite part K4377007.
SDS page result
After expression, we conducted SDS PAGE to verify the protein was produced.
Test
Functional test
We used EDTA-Fe and H2O2 to catalyze dityrosine bonding, as figures show that our sample(Composite part K4377007 ) has significant aggregation compared to the control (mRFP), since the bonding between tyrosines occurs when the C-H bond on the benzene ring breaks and forms C-C bonding, we decided to analyze the region of C-H bond in FTIR data
