Constitutive FadR expression and regulated promoter

Const. FadR generator (BBa_K861052 contains promoter, RBS, FadR) - FadR promoter (BBa_K861060)- RBS (BBa_K3096000). FadR binds DNA and represses gene expression for beta-oxidation in the absence of long chain Acyl-CoA

Background

The intake of a fatty meal increases the fatty acid availability within the body and therefore their metabolite Acyl-CoA will increase. Long chain Acyl-CoA will bind constitutively expressed FadR and hence inhibits its activity (Feng et al. 2012). FadR is the repressor of the promoter pFad

Biology and Usage

The FadR expression system of E.Coli senses Acyl-CoA and activates fatty acid transport genes in vivo (Feng et al. 2012).
