Structures of ParB bound to DNA reveal mechanism of partition complex formation
Article Abstract:
Structures of ParB bound to partition sites where ParB forms an asymmetric dimer with extended amino-terminal helix-turn-helix domains that contact A-boxes are described. These structural features of ParB explain how the protein can bind complex arrays of A and B-box elements on adjacent DNA arms of the looped partition site.

Segrosome structure revealed by a complex of ParR with centromere DNA
Article Abstract:
The structure of the pSK41 segrosome exposed in the crystal structure of ParR-DNA complex is presented. The dimer-of-dimers unite in a continuous protein super-helical array, covering the DNA about its positive convex surface, indicating a system for ParM capture and subsequent plasmid segregation.

Structure of the gated domain of a CA2+-activated K+ channel complexed with Ca2+/calmodulin
Article Abstract:
Research into the gating of small-conductance Ca2+-activated K+ channels (SK channels) is described. The study indicates a potential gating mechanism for the SK channel CaMBD/Ca2+/CaM complex.
