Part:BBa_K4129002

Promoter of the Aspergillus niger FDH gene

The part consists of the 1000 bp upstream of Formate Dehydrogenase (FDH) CDS from Aspergillus niger. Since FDH genes have been shown to be upregulated in response to furfural in Saccharomyces cerevisiae, the part was utilised to test if anFDH promoter is also responsive to furfural. Quantification by qPCR of the FDH transcript and mCherry transcript from a transiently expressed BBa_K4129005 (BBa_K4129002 regulating mCherry reporter), showed that BBa_K4129002 is induced by furfural both in its native regulatory enviroment (Fig. 1 A) and when used in syntetic expression cassettes (Fig 1 B).
