Fig. 2: The profile of most common chemosensory classes in Spirochaetota.
From: Atypical chemoreceptor arrays accommodate high membrane curvature

The three major taxonomy classes are colored: Leptospirae (red), Brachyspirae (purple), and Spirochaetia (green). Species found in MiST3 are represented by their species and strain name. The profile shows the presence of the common chemotaxis classes F1(blue), F8(orange), F2 (green), and F7(red). The systems with CheW-CheRlike (F2 systems) are marked with a black outline. An additional high-resolution figure is separately available.
