Metrics of the top motif identified by MEME searches of transcription termination sites. a Motif 2 was conserved in tail-to-tail intergenic regions in four Theileria species (Tp = Theileria parva; Ta = Theileria annulata; To = Theileria orientalis; Te = Theileria equi) and b peaked in distribution at transcription termination sites genome-wide in T. parva. The horizontal axis represents sequence areas from -1,000 bp upstream to +1,000 bp downstream around transcription initiation sites with single nucleotide resolution. Position 0 represents the transcription termination site. The vertical axis represents the frequency of the motif
