SMC condensin: promoting cohesion of replicon arms

Two studies using chromosome conformation capture (3C) analyses in the Gram-positive bacterium Bacillus subtilis have revealed a global pattern of chromosome organization that originates from loading sites of the Smc–ScpAB complex. Loading Smc–ScpAB at a single genomic location is sufficient to promote genome-wide folding of DNA into a well-defined structure.
