Composite part of BBa_K801010, BBa_K801072 and BBa_K801012
Keywords: caffeine, TEF2, expression cassette


Abbreviations:

  • CaDXMT1 = coffea arabica 3,7-dimethylxanthine N-methyltransferase 1

Design Notes

Related BioBrick: BBa_K801072 BBa_K801077

Quality control measures:

  • Test digest has been performed with Xba1 and Pst1 (see mainpage)
  • Part was totally sequenced

Backbone:

  • Backbone name: pSB1C3'
  • Resistance Cp

Protein coding:

  • CaDXMT1

Enzymatic activity: 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 BioBricks BBa_K801073 and BBa_K801074 are 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.
