Parts to make

  • [http://openwetware.org/wiki/Protein_purification_tags Protein purification tags]
  • [http://openwetware.org/wiki/BBRFC14 Protein domains parts]
  • [http://openwetware.org/wiki/SynBERC:MIT/Calendar/2007-8-8 Wishlist of wanted parts]
  • [http://ca.expasy.org/tools/peptidecutter/peptidecutter_enzymes.html ExPASy PeptideCutter]: The cleavage specificities of selected enzymes and chemicals
  • From Ron: KT3, His, VSV-G, S-tag, V5, HSV, T7, DDDK, Glu-Glu, HA, E-tag, Myc
    • Of these tags, I think the widely used ones are FLAG, His, Myc, HA, and V5.

Parts that have been designed

The optimal second codon is AAA (Lys) in E. coli. So perhaps make all head domains start with Met-Lys?

Codon selection

Rare is defined as less than 5%. Also checked Xenopus, human, mouse, B. subtilis, Drosophila, C. elegans, Pichia, Trichoplusia.
