Secondary structure prediction and motifs of B. subtilis SMC-like proteins. The secondary structure B. subtilis SMC-like proteins [SMC, RecN, SbcC (also termed YirY) and SbcC2 (YhaN)] and its comparison with E. coli SbcC (EcoSbcC) and human Rad50 (HsRad50) were predicted using the COILS program (www.ch.embnet.org/software/COILS_form.html). The Walker A and B motifs and the CXXC and GGXXXGG motifs necessary for dimerization of Rad50, SbcC, EcoSbcC and SMC proteins, respectively, are indicated. The putative dimerization (Leu rich) motif of RecN is also indicated. Abbreviation: aa, aminoacids.
