Representation of apoClfBN2N3(199–542). A, domain organization of Clf-Sdr proteins. S, signal peptide; A, ligand binding region; B, homologous repeats; R, SD repeats; W, wall-spanning region; M, membrane anchor; C, cytoplasmic tail. B, ribbon representation of structure of the apo-form of ClfB. The N2 and N3 subdomains are shown in green and yellow, respectively. C, representation of the two symmetry-related molecules in the unit cell. The latch of the molecule A (yellow) is inserted in the latching trench of molecule B (green) and vice versa.
