The fungal synthetic transcription factor, FunsTF01 (LexA-LL-HbaR-B112-SV40)
FunsTF01 is a synthetic transcription factor (sTF) based on a sensor of benzoic acid derivatives (sBAD), which is a sTF in S. cerevisiae (Castaño-Cerezo et. al (2020)). FunsTF01 deviates from sBAD, in that it has a nuclear localization signal (NLS) and is codon optimised to A. niger
FunsTF01 is designed to function as a transcription factor that can initiate transcription from the 6xLexO minimal promoter (BBa_K4129115). This sTF is designed to be the sensing part of a biosensor.
FunsTF01 is a fusion protein consisting of the DNA-binding domain from LexA, the ligand sensing domain from HbaR, transactivation domain B112 and the NLS SV40. The linker between the LexA domain and the HbaR domain is a longer linker (Ottoz et. al (2014) compared to the linker in sBAD, which was the reference sTF (Castaño-Cerezo et. al (2020)).
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)).
The transactivation domain B112 is from E. coli, and it was experimentally proven to initiate transcription of a synthetic promoter in S. cerevisiae (Ottoz et. al (2014)). The NLS SV40 is a small peptide sequence of PKKKRKV that enables transport of the protein to the nucleus (Garcia-Bustos et. al (1991)).
