FIGURE 1: Structures of B. subtilis (top) and S. aureus (bottom) EzrA cytoplasmic domains.
The five ~100 amino acid triple helical bundle repeat units in B. subtilis EzrA are coloured alternately red and blue; the terminal 4 helical bundle is coloured green. The S. aureus EzrA structure is an N-terminal fragment of the cytoplasmic domain, encompassing just two of the five triple helical bundle units.
