Figure 1.

Babesia bovis rom4 locus. A section of chromosome 2 (nt. 1,336,694 to 1,384,167) containing the paralogs in Table 1. (4.1, 4.2, 4.3, 4.4 and 4.5, yellow rectangles) is shown in scale. Genes coding for proteases or protease-related functions (U: ubiquitin fusion degradation protein; T: threonine protease of the 20S proteasome; S: subtilisin-like protease) are marked in green. Orfs not related to proteases are marked in orange and intergenic regions in grey. Arrows mark the orientation of the rom4 orfs.
