Note(s): We assigned a putative transcription start site to this promoter based on the observation that the majority of the promoters, whose transcription start sites were determined experimentally, present a distance of 6 nucleotides between the transcription start site and the -10 box.
Lewis LK,1992predicted a potential dinG promoter site (-35 and -10 regions) by using three different computational search programs. The putative transcription start site of this promoter overlaps the dinG gene, but the start of the translation of this gene has not been determined.

Note(s): In conjunction with gene expression analysis, it can be argued that the ybiB and dinG genes form an operon regulated by LexA Kaleta C,2010
Based on crystallization analysis and EMSA, it was determined that YbiB binds to DNA with high affinity. The ybiB gene is under LexA control and is induced by DNA-damaging agents Schneider D,2015.
