The phosphate clamp: a small and independent motif for nucleic acid backbone recognition.

abstract：:Regulation of gene expression influences almost all biological processes in an organism; sequence-specific DNA-binding transcription factors are critical to this control. For most genomes, the repertoire of transcription factors is only partially known. Hitherto transcription factor identification has been largely bas...
