ALD, average length of the predicted folding domains; ALB, average length of the inter-operonic regions containing folding-domain boundaries; ALNB, average length of the remaining inter-operonic regions. #HEG is the number of highly expressed genes encoded in the predicted folding-domain boundary regions. #NAP is the number of NAP binding sites in the inter-operonic regions containing a predicted folding-domain boundary. #Transcription factories is the number of superstructures near predicted folding-domain boundaries formed by NAPs associated with the ribosomal RNA operons. #Fis is for the number of Fis binding sites in the inter-operonic regions containing a predicted folding-domain boundary.
