Bacillus subtilis RecN binds and protects 3'-single-stranded DNA extensions in the presence of ATP.

abstract：:In silico prediction of transcription factor binding sites (TFBSs) is central to the task of gene regulatory network elucidation. Genomic DNA sequence information provides a basis for these predictions, due to the sequence specificity of TF-binding events. However, DNA sequence alone is an impoverished source of infor...
