Writing to DNA
Outline
- Goal: To change to sequence of DNA at a specific locations
- Approaches:
- Site-specific double-stranded break
- Error-prone DNA polymerase
- Site-specific recombinases
- Classification by functions (analogous): transposase, invertase, resolvase, integrase
- Classification by structures (homologous): tyrosine recombinase, serine recombinase
- Site-specific double-stranded break
- DSB activate repairing mechanism, especially homologous recombination
- custom-made Zn-finger binding protein
- Error-prone DNA polymerase
- targeted by ORI on plasmid
- invivo directed evolution
- Site-specific recombinase: by function and by structures
- transposase
- invertase
- resolvase
- integrase
- excisionase
- Tyrosine-recombinase, Serine recombinase (comparison)
- Engineering perspective: what do engineer wanna know
- reversibility/ efficiency
- specificity
- speed
- modularity (for protein engineer)
- Data-management
- Goal: to have a well-organized system to compare/contrast these machinery
- Demand: what information do we want as an engineer
- Supply: what kind of information exist
- our parallel experiment
- literature: (reference system, split rawdata and inference)
- public database like PDB, GenBank
- review paper
- experimental paper
- how should our "table" look like
- need to take into account uncertainity of inference
- capture the recurring pattern of experiment / raw data
- The Database project..for site-specific recombinase..and maybe other DNA-writer
- Need more quantitative information, more standardized information
- source of information: literature + parallel experiment
- What do we need in our table:
