Structure of a bacterial type IV secretion core complex at subnanometre resolution [PDF]

, 2013
Type IV secretion (T4S) systems are able to transport DNAs and/or proteins through the membranes of bacteria. They form large multiprotein complexes consisting of 12 proteins termed VirB1-11 and VirD4.

Electron Transport Chain Complex II Regulates Steroid Metabolism

iScience, 2020
Summary: The first steroidogenic enzyme, cytochrome P450-side-chain-cleavage (SCC), requires electron transport chain (ETC) complexes III and IV to initiate steroid metabolic processes for mammalian survival.

Dissection of the asynchronous transport of intestinal microvillar hydrolases to the cell surface [PDF]

, 1988
Novel subcellular fractionation procedures and pulse-chase techniques were used to study the intracellular transport of the microvillar membrane hydrolases sucrase-isomaltase and dipeptidylpeptidase IV in the differentiated colon adenocarcinoma cell line

Transport of proteins into mitochondria [PDF]

, 1985
Translocational intermediates of precursor proteins of ATPase F1β subunit and cytochrome c1 across mitochondrial membranes were analyzed using two different approaches, transport at low temperature and transport after binding of precursor proteins to ...

Mitochondrial morphology is associated with respiratory chain uncoupling in autism spectrum disorder

Translational Psychiatry, 2021
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is associated with unique changes in mitochondrial metabolism, including elevated respiration rates and morphological alterations.

Arrangement of electron transport chain components in bovine mitochondrial supercomplex I1III2IV1 [PDF]

, 2011
The respiratory chain in the inner mitochondrial membrane contains three large multi-enzyme complexes that together establish the proton gradient for ATP synthesis, and assemble into a supercomplex.

Enhancing mitochondrial activity in neurons protects against neurodegeneration in a mouse model of multiple sclerosis

eLife, 2021
While transcripts of neuronal mitochondrial genes are strongly suppressed in central nervous system inflammation, it is unknown whether this results in mitochondrial dysfunction and whether an increase of mitochondrial function can rescue ...

Tissue-specific mitochondrial HIGD1C promotes oxygen sensitivity in carotid body chemoreceptors

eLife, 2022
Mammalian carotid body arterial chemoreceptors function as an early warning system for hypoxia, triggering acute life-saving arousal and cardiorespiratory reflexes. To serve this role, carotid body glomus cells are highly sensitive to decreases in oxygen

Electron optics in ballistic graphene [PDF]

, 2015
This thesis is centered on the experimental observation of electron-optics phenomena in graphene. In Chapter 2, graphene is introduced and the ability to form p-n junctions, with particular regard to electron optics experiments, is discussed.
