Composite part of BBa_K801010, BBa_K801070, BBa_K801012, BBa_K319003, BBa_K801071 and BBa_K801012


Keywords: caffeine, TEF1, TEF2, ADH1, expression cassette


Abbreviations:

  • CaXMT1 = coffea arabica xanthosine N-methyltransferase 1
  • CaMXMT1 = coffea arabica 7-methylxanthine N-methyltransferase 1

Design Notes

Related BioBrick: BBa_K801070 BBa_K801071 BBa_K801077

Quality control measures:

  • Test digest has been performed with use of Xba1 and Pst1 (see mainpage)

Backbone:

  • Backbone name: pSB1C3'
  • Resistance: Cp

Protein coding:

  • Protein: CaXMT1-Strep-tag and CaMXMT1-Strep-tag


Enzymatic activity: EC-number [http://enzyme.expasy.org/EC/2.1.1.158 2.1.1.158] EC-number [http://enzyme.expasy.org/EC/2.1.1.160 2.1.1.160]


Cytotoxicity:
This Biobrick is one part of the pathway, which leads to caffeine (the BioBrick BBa_K801075 is further needed). We investigated the toxicity of caffeine and found out, that the growth of yeast strains was inhibited at concentrations of 10 mM. Caffeine with a concentration of 100 mM even showed a lethal effect on yeast cells. Lower concentrations of caffeine (range of micro molar) did not show any growth inhibition or effect.

Safety notes:
