Promoter Library

Introduction

As a part of our project we wish to create a library of SigmaA promoters and characterise them based on their stregnths.

Novelty in this sub-project

A library of promoters with different strengths would be very useful for engineering biological devices. Promoters' strength can be compared with their PoPS values. However measuring the PoPS is not a trivial process. We can instead meausure their strengths relatively.

Template used to create the promoter sequences: Prefix...UpSpacer...-35...PromSpacer...-10...DownSpacer..Suffix

  • BBPrefix - StandardBioBrickPrefix EcoR1 and Xba1 - gaattcgcggccgcttctagag
  • UpSpacer - attta - consensus sigA 5 bases 5'
  • -35 - TTGACA
  • PromSpacer - length 17 - consensus ttttatttaaattatga
  • -10 - TATAAT
  • DownSpacer (from ackA)- ggaaaag
  • BBSuffix - Standard BioBrick suffix Spe1 and Pst1 - tactagtagcggccgctgcag
