Abstract: | A systematic search for motifs associated with CcrM DNA methylation sites revealed four long (>100-bp) motifs (CIR sequences) present in up to 21 copies in Caulobacter crescentus. The CIR1 and CIR2 motifs exhibit a conserved inverted repeat organization, with a CcrM site in the center of one of the repeats. |
