Storage of solar energy in the thylakoid electrical field by photosynthesis in vivo can substantially destabilize charge-separated states in photosystem II, leading to singlet oxygen production and photodamage, contributing to loss of productivity, especially under fluctuating light experienced in the field.

Single cell, fluorescent microscopy and mathematical modeling reveal how bacterial flagella dynamically assemble outside the cell.

Crystallography and single particle cryo-EM reveal hexameric and pentameric structures of the ExbBD energizer in the Ton system and oligomeric transition, which provides a unique working mechanism and a new vision of dynamic membrane biology.

Elastic forces generated by the giant protein titin define both passive and active tension of skeletal muscle fibers and protect the sarcomeric myosin filaments from severe disruption during contraction.

High-performance computing simulations reveal how two remote sites in the multidrug transporter AcrB work together for drug extrusion using the proton-motive force.

Genetically altering the size of the molecular spring element in the giant protein titin established that titin determines the stiffness of skeletal muscle and the number of sarcomeres in series.

Optogenetic reconstitution reveals core functional modules and architecture of the cortical force-generating machinery in human cells.

Evidence is presented that supports a completely new, diffusion-driven mechanism for transporting proteins across membranes in bacteria.

Sec1/Munc18-family proteins chaperone SNARE assembly via a common templating mechanism.

The motor protein kinesin utilizes its fuel molecule by active and concerted motions of its subdomains, while it rapidly interacts with the microtubule track by forming a wet and dynamic interface.
