This is a device that uses a stable glucose binding protein (GBP) flanked with two compatible fluorescent proteins to indicate glucose levels with a fluorescent resonance energy transfer (FRET) based actuator. The device input is glucose-binding and the device output is fluorescent spectra of the two flurophore. FRET was achieved using mRuby3 as the acceptor fluorophore and cometGFP as the donor fluorophore. Upon glucose binding, this device will undergo a conformational change such that the cometGFP protein in an excited state would transfer energy to the acceptor mRuby3 to be emitted. Quantifying this excitation/emission pair would reveal the extent to which FRET and thus glucose binding that had occurred, relative to the open, unbounded state.

6 Amino Acid Fusion Protein Linker
2016-12-11T12:00:00Z
2016-12-11T04:55:01Z
Linker sequence was suggested and provided by our TA, Salil Bahte, and then optimized for use in E. coli.
This sequence encodes for six amino acids that constitute the fusion protein linker for our Stanford BioE44 DNA construct. It is optimized for use in E. coli, and is designed to maintain linearity of the sequence and prevent protein folding. Our design relied on proper orientation of two GBP domains linked on each end to a flurophore. The linkers were included to ensure that glucose-binding caused the conformational change characterized with FRET instead of inherently folded protein structure, the linkers were included.

Codon optimization software was used since we transformed our plasmid into E. coli. Also, the linker needed to be relatively short since we were already designing a long construct and needed to minimize the synthesis time given class constraints.

mRuby3 fluorescent protein

mRuby3 is a brighter and more photostable variant of a red fluorescent protein developed by Bryce T. Bajar et al. According to their February 2016 study, mRuby3 has a maximum excitation wavelength of 558 nm, and a maximum emission wavelength of 592 nm. It can be used in FRET analysis as an acceptor fluorophore when paired with a GFP such as cometGFP.

Glucose Binding Protein of Thermus thermophilus
2016-12-11T12:00:00Z
2016-12-11T05:29:45Z
This GBP comes from the genomic sequence of Thermus thermophilus. The complete bacterial genome was published by Henne et al. in Nature Biotechnology in 2004 (https://www.ncbi.nlm.nih.gov/pubmed/15064768), and the particular GBP was characterized in a 2006 study by Cuneo et al. in the Journal of Molecular Biology (https://www.ncbi.nlm.nih.gov/pubmed/16904687).
This bacterial glucose binding protein (GBP) is derived from the genome sequence of Thermus thermophilus that was published in 2004 by Henne et al. In 2006, Cuneo et al. analyzed the sequence of this particular GBP, determined its X-ray crystal structure and characterized the stability of glucose-binding. The GBP is composed of two domains separated by a hinge, maintaining an open conformation when unbound to glucose and a closed conformation when bound. When flanked with an RFP fluorophore on the N-terminus and a GFP fluorophore on the C-terminus, these conformation changes facilitated FRET-based analysis of glucose binding. In addition, this GBP was selected for its reasonably short sequence length (1242bp) and stable glucose binding ability (Kd value of 0.08(+/- 0.03) mM). According to Cuneo et al., this T. thermophilus GBP shares more structural homology with maltose binding proteins than glucose binding proteins. However, we were able to obtain FRET when glucose was added, suggesting that glucose is a ligand for this protein.

This GBP sequence was optimized for use in E. coli. Also, start and stop codons were removed to facilitate fusion to the other components of our construct.
