Regulatory elements in ipaH upstream regions (a) Alignment of the upstream region for selected representatives of the ipaH class #4. Representatives have been selected based on their sequences so that all sequence variants are presented. The putative MxiE box is indicated by the orange box, A/T tracks are in green boxes. The transcription start is indicated by the black arrow. (b) Comparison of the sequence-based ipaH classification with the classification based on positioning of the MxiE box, − 10 element, and the sequence of the spacer. Adapted from34. (c) Principal scheme of upstream regions of the ipaH classes #9a and #9b.
