OVERVIEW


The goal of our project was to design and construct a biosensor for macrolide detection and quantification.


  • Our basic parts include: ermC, mphr, pMphR, egfp and RBS associated with pMphR
  • Our composite parts include: Biosensor for erythromycin detection

PARTS


Basic Parts


ermC: BBa_K3386000


ermC is a methyltransferase, which introduces dimethylation of the adenine residue in 23S rRNA at position 2085, thus preventing binding of macrolide and lincosamide antibiotics [1].


mphR: BBa_K3386001


A mphr gene encoding a repressor protein binding pMphR promoter sequence preventing the transcriptions of genes under it [2].


pMphR: BBa_K3386002


A pMphR promoter sequence, which naturally drives transcription of mphr, a macrolide antibiotics resistance gene [3].


egfp: BBa_K3386003


EGFP is an enhanced green fluorescence protein [4].


RBS: BBa_K3386005


RBS associated with pMphR naturally allows translation of the Mph(A) gene [3].

Composite Parts


Biosensor for Erythromycin Detection: BBa_K3386004


Our composite part is a biosensor device for erythromycin detection.
