The fungal synthetic transcription factor, FunsTF63 (LexA-LL-HbaR9-VP16-SV40)

FunsTF63 is a synthetic transcription factor (sTF). FunsTF63 should initiate the transcription through the 6xLexO minimal promoter. This sTF is designed to be the sensing part of the biosensor.

FunsTF63 is a fusion protein consisting of the DNA-binding domain from LexA, the ligand sensing domain from HbaR9, the transactivation domain from VP16 and the nuclear localization signal (NLS) SV40. The linker between LexA and HbaR9 is a longer linker (Ottoz et. al (2014) compared to the linker used in sBAD, which was the reference sTF (Castaño-Cerezo et. al (2020)). FunsTF63 was codon optimised to A. niger.

LexA is a repressor that regulates the SOS response in E. coli (Radman. 1975). LexA binds to a specific DNA motif, namely LexO sites (Erill. et al (2003)). HbaR is a transcription factor from Rhodopseudomonas palustris that initiates transcription in the presence of benzoic acid (Egland. et al (2000) or in the presence of benzoic acid derivatives (Castaño-Cerezo et. al (2020)). We created 16 mutants of HbaR and FunsTF63 carried mutant 9 of HbaR, which had the following mutations: L64V, F85T, A88G, A90Y, Y96H and L97G

Viral Protein 16 (VP16) from Herpes simplex virus type 1 is a transcription factor with a transactivation domain that recruits RNA polymerase II (Hirai et al. (2010)).The NLS SV40 is a small peptide sequence of PKKKRKV that enables transport of the protein to the nucleus (Garcia-Bustos et. al (1991)).

The intented function was not proven in A. niger.
