Transcription of ribosomal protein genes in the str-spc region in Escherichia coli seems to be exclusively anticlockwise. Insertion mutations in this region inactivate many but not all distal ribosomal protein genes. Thus, there seems to be more than one transcriptional unit for the ribosomal protein genes in this region.
