Schematic of domains found within O. tsutsugamushi strain Ikeda Anks. Each Ank is listed by name, followed by its gene annotation in parentheses. The amino acid locations of ankyrin repeats, putative F-boxes, coiled-coil domains, signal peptides, and PRANC domains are noted above or below the corresponding shape. F-boxes predicted using the SMART algorithm are found within PRANC domains, while those found via manual sequence searches are shown as separate boxes. The length of each Ank is noted to the right of its respective schematic, with the estimated protein size. Though Ank18 does not contain any ankyrin repeats itself, it is annotated as an Ank because it shares homology with nonrepeat regions of O. tsutsugamushi strain Boryong Ank1u7 (OTBS_1195), which does contain ankyrin repeats. aa, amino acids.
