1 BioBricks

2 Part Types Chassis – organism (E. coli, yeast, mammalian)
Vectors – plasmids, strains Parts - Proteins, RBS Devices – Inverters, reporters

3 Chassis Constructing systems in bacteria (E. coli)
This chassis can interact with most other organisms Conjugation, bacteriophage, signalling etc.

4 Vectors Plasmid – circle of extra chromosomal DNA that can be inserted into cells These can contain biobrick pieces or be a “backbone” into which one can place biobrick pieces Strains?

5 Parts Protein Coding Regulatory Ribosome Binding Sites Terminators RNA
Conjugation Regulatory Terminators RNA DNA

6 Regulatory

7 Terminators

8 RNA Nature Biotechnology 22, (2004)

9 DNA Spacers Add Biobricks site Insertion Transpososome

10 Protein coding Genes that code for useful proteins
Repressors, activators Integrases, Excisionases Enzymes Reporters

11 Ribosome binding sites
Site where the ribosome binds (obviously) Different sequences lead to change in translation These sites can be used for riboregulators or other regulation

12 Conjugation Genes and plasmids for the transfer of genetic material via conjugation. kentsimmons.uwinnipeg.ca/16cm05/1116/16monera.htm

13 Devices Protein Generator Reporters Composite Devices Inverters
Signalling Protein Generator Composite Devices Measurement

14 Reporters Semi-rudundant to DNA as there are genes of reporters in this category Also reporters expressed by constitutive and regulated promoters Some more complex systems using reporters

15 Inverters, Logic devices
PoPs -Polymerase Per Second (or PoPS) is defined as the number of times that an RNA polymerase molecule passes a specific point on DNA per unit time

16 Signalling Communication between an individual cell and its neighbors
Signal Senders Signal Receivers devices using signalling

17 Protein Generation RBS-gene-terminator promoter-RBS-gene-terminator
operator-promoter-RBS-gene-terminator

18 Composite devices Catch all device category

19 Measurement Promoter output measurements RBS characterization
QPI refers to a Quad-Part Inverter: an RBS, repressor protein, terminator and promoter Screening plasmids: promoter, reporter, cloning site, reporter

20 “Other” PCR primers Tags – degradation, binding and restriction sites
