Insights into transport mechanism from LeuT engineered to transport tryptophan [PDF]
The EMBO Journal, 2011 LeuT is a bacterial homologue of the neurotransmitter:sodium symporter (NSS) family and, being the only NSS member to have been structurally characterized by X-ray crystallography, is a model protein for studying transporter structure and mechanism. Transport activity in LeuT was hypothesized to require structural transitions between open-to-out and ...

Simulink Model of a Thermoelectric Generator for Vehicle Waste Heat Recovery
Applied Sciences, 2021 More than 50% of the energy released through combustion in the internal combustion engine (ICE) is rejected to the environment. Recovering only a part of this energy can significantly improve the overall use of resources and the economic efficiency of ...

Topologically Protected Transport in Engineered Mechanical Systems
, 2022 Mechanical vibrations are being harnessed for a variety of purposes and at many length scales, from the macroscopic world down to the nanoscale. The considerable design freedom in mechanical structures allows to engineer new functionalities. In recent years, this has been exploited to generate setups that offer topologically protected transport of ...

Chemophoresis engine: A general mechanism of ATPase-driven cargo transport
PLOS Computational Biology, 2022 Cell polarity regulates the orientation of the cytoskeleton members that directs intracellular transport for cargo-like organelles, using chemical gradients sustained by ATP or GTP hydrolysis. However, how cargo transports are directly mediated by chemical gradients remains unknown.
