Active Nuclear Import of Membrane Proteins Revisited
It is poorly understood how membrane proteins destined for the inner nuclear membrane pass the crowded environment of the Nuclear Pore Complex (NPC). For the Saccharomyces cerevisiae proteins Src1/Heh1 and Heh2, a transport mechanism was proposed where ...

Evaluation of four different strategies to characterize plasma membrane proteins from banana roots [PDF]
Plasma membrane proteins constitute a very important class of proteins. They are involved in the transmission of external signals to the interior of the cell and selective transport of water, nutrients and ions across the plasma membrane.

Electron transport and light-harvesting switches in cyanobacteria
Cyanobacteria possess multiple mechanisms for regulating the pathways of photosynthetic and respiratory electron transport. Electron transport may be regulated indirectly by controlling the transfer of excitation energy from the light-harvesting ...

Escherichia coli TatA and TatB Proteins Have N-out, C-in Topology in Intact Cells [PDF]
The twin arginine protein transport (Tat) system translocates folded proteins across the cytoplasmic membrane of prokaryotes and the thylakoid membrane of chloroplasts.

In kinetoplastid protists, several metabolic pathways, including glycolysis and purine salvage, are located in glycosomes, which are microbodies that are evolutionarily related to peroxisomes.

The endocytic degradation of plasma membrane proteins can be modulated by deubiquitylating enzymes (DUBs). Here, the authors describe two plasma membrane localized Arabidopsis DUBs that can be activated by binding to anionic lipids and influence the ...

Transport of Cytoplasmically Synthesized Proteins into the Mitochondria in a Cell Free System from Neurospora crassa [PDF]
Synthesis and transport of mitochondrial proteins were followed in a cell-free homogenate of Neurospora crassa in which mitochondrial translation was inhibited. Proteins synthesized on cytoplasmic ribosomes are transferred into the mitochondrial fraction.

Biogenesis of mitochondrial porin [PDF]
We review here the present knowledge about the pathway of import and assembly of porin into mitochondria and compare it to those of other mitochondrial proteins.

Crystal structure of an archaeal CorB magnesium transporter
CNNM/CorB proteins are a conserved family of membrane proteins associated with Mg2+ transport. Here, structures of an archaeal CorB protein in apo state and with Mg2+-ATP bound and accompanying biophysical experiments suggest direct Mg2+ transport by ...

Functional characterization and discovery of modulators of SbMATE, the agronomically important aluminium tolerance transporter from Sorghum bicolor. [PDF]
About 50% of the world's arable land is strongly acidic (pH ≤ 5). The low pH solubilizes root-toxic ionic aluminium (Al3+) species from clay minerals, driving the evolution of counteractive adaptations in cultivated crops.
