I-ApeKI [corrected]: a novel intron-encoded LAGLIDADG homing endonuclease from the archaeon, Aeropyrum pernix K1.

abstract：:Transcription factor decoy binding sites are short DNA sequences that can titrate a transcription factor away from its natural binding site, therefore regulating gene expression. In this study, we harness synthetic transcription factor decoy systems to regulate gene expression for metabolic pathways in Escherichia col...
