Basic mechanisms for recognition and transport of synaptic cargos

open access: yesMolecular Brain, 2009
Synaptic cargo trafficking is essential for synapse formation, function and plasticity. In order to transport synaptic cargo, such as synaptic vesicle precursors, mitochondria, neurotransmitter receptors and signaling proteins to their site of action ...

Is the Cell Really a Machine? [PDF]

open access: yes, 2019
It has become customary to conceptualize the living cell as an intricate piece of machinery, different to a man-made machine only in terms of its superior complexity.

Molecular motors in nanobiotechnology: Protein and DNA based molecular motors: A review

open access: yesResults in Chemistry
Molecular motor can be defined as the collection of a separate number of molecular features (that is, a supramolecular structure) which has been developed to carry out a function through the mechanical movements of its components, which occurs when it is appropriately stimulated externally. Therefore, molecular motors include a part with a motor, which

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

A Master equation approach to modeling an artificial protein motor

open access: yes, 2010
Linear bio-molecular motors move unidirectionally along a track by coordinating several different processes, such as fuel (ATP) capture, hydrolysis, conformational changes, binding and unbinding from a track, and center-of-mass diffusion.

Prime movers : mechanochemistry of mitotic kinesins [PDF]

open access: yes, 2014
Mitotic spindles are self-organizing protein machines that harness teams of multiple force generators to drive chromosome segregation. Kinesins are key members of these force-generating teams.

Selective cell-surface labeling of the molecular motor protein prestin [PDF]

open access: yesBiochemical and Biophysical Research Communications, 2011
Prestin, a multipass transmembrane protein whose N- and C-termini are localized to the cytoplasm, must be trafficked to the plasma membrane to fulfill its cellular function as a molecular motor. One challenge in studying prestin sequence-function relationships within living cells is separating the effects of amino acid substitutions on prestin ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Engineering molecular machines

open access: yesNew Journal of Physics, 2016
Biological molecular motors use chemical energy, mostly in the form of ATP hydrolysis, and convert it to mechanical energy. Correlated thermal fluctuations are essential for the function of a molecular machine and it is the hydrolysis of ATP that ...

Transcriptional Reorganization of Drosophila Motor Neurons and Their Muscular Junctions toward a Neuroendocrine Phenotype by the bHLH Protein Dimmed

open access: yesFrontiers in Molecular Neuroscience, 2017
Neuroendocrine cells store and secrete bulk amounts of neuropeptides, and display morphological and molecular characteristics distinct from neurons signaling with classical neurotransmitters.
