Abstract..

Cells can sense and respond to the presence of various gas molecules such as oxygen, nitrogen and carbon monoxide using gas sensor proteins. CooA is a carbon monoxide (CO) sensing transcription factor. It is a member of the cAMP receptor protein (CRP)/fumavate nitrate reduction (FNR) family of transcriptional regulators. CooA switches on oxidation enzymes in Rhodospirillum rubrum (a purple, nonsulfur, phototrophic bacterium) which enables the bacterium to use CO as a carbon source. CO is an odorless and colorless gas which can be extremely lethal. Our aim is to develop a cell sensor which can detect a wide range of CO concentration in the environment. We are building CooA and CooA-responsive promoter biobricks which will be transformed into E.coli. Fluorescent proteins (GFP and RFP) will be utilized as dose-responsive signals of ambient CO.Read More...
