THE INGENIOUS STRUCTURE OF CENTRAL ROTOR APPARATUS IN VOV1; KEY FOR BOTH COMPLEX DISASSEMBLY AND ENERGY COUPLING BETWEEN V1 AND VO.

The ingenious structure of central rotor apparatus in VoV1; key for both complex disassembly and energy coupling between V1 and Vo.

Vacuolar type rotary H+-ATPases (VoV1) couple ATP synthesis/hydrolysis by V1 with proton translocation by Vo via rotation of a central rotor apparatus composed of the V1-DF rotor shaft, a socket-like Vo-C (eukaryotic Vo-d) and the hydrophobic rotor ring.Reconstitution experiments using subcomplexes revealed a weak binding affinity of V1-DF to Vo-C

Random sub-diffusion and capture of genes by the nuclear pore reduces dynamics and coordinates inter-chromosomal movement

Hundreds of genes interact with the yeast nuclear pore complex (NPC), localizing at the nuclear periphery and clustering with co-regulated genes.Dynamic tracking of peripheral genes shows that they cycle on and off the NPC and that interaction with the NPC slows their sub-diffusive movement.Furthermore, NPC-dependent inter-chromosomal clustering le
