Road to Ruin: Targeting Proteins for Degradation in the Endoplasmic Reticulum [PDF]

open access: yes, 2011
Some nascent proteins that fold within the endoplasmic reticulum (ER) never reach their native state. Misfolded proteins are removed from the folding machinery, dislocated from the ER into the cytosol, and degraded in a series of pathways collectively ...

Quantification and fatty acid profiles of sulfolipids in two halophytes and a glycophyte grown under different salt concentrations [PDF]

open access: yes, 2004
This study was aimed at understanding the role of sulfolipids in salt tolerance mechanisms of the halophytes Aster tripolium L., Compositae, and Sesuvium portulacastrum L., Aizoaceae, and of the glycophyte Arabidopsis thaliana (L.) Heynh., Brassicaceae ...

The Third Sodium Binding Site of Na,K-ATPase Is Functionally Linked to Acidic pH-Activated Inward Current [PDF]

open access: yes, 2018
Sodium- and potassium-activated adenosine triphosphatases (Na,K-ATPase) is the ubiquitous active transport system that maintains the Na+ and K+ gradients across the plasma membrane by exchanging three intracellular Na+ ions against two extracellular K ...

N-terminal Domains of Human Copper-transporting Adenosine Triphosphatases (the Wilson’s and Menkes Disease Proteins) Bind Copper Selectively in Vivo and in Vitro with Stoichiometry of One Copper Per Metal-binding Repeat*

open access: yesJournal of Biological Chemistry, 1997
N-terminal domains of the Wilson’s and Menkes disease proteins (N-WND and N-MNK) were overexpressed in a soluble form in Escherichia coli as fusions with maltose-binding protein, purified, and their metal-binding properties were characterized. Both N-MNK

LEAD-ADENOSINE TRIPHOSPHATE COMPLEXES IN ADENOSINE TRIPHOSPHATASE HISTOCHEMISTRY [PDF]

open access: yesJournal of Histochemistry & Cytochemistry, 1969
Chelation of lead by adenosine triphosphate (ATP) and its consequences for adenosine triphosphatase histochemistry were examined. The formation constant of lead-ATP chelates was found by two methods to be 4.6-4.7 x 104. The characteristics of enzyme inhibition by lead were consistent with the predicted effects of lead-ATP chelation.

Carcinogenic oestrogens induce respiration deficiency mutation in yeast [PDF]

open access: yes, 1991
In addition to hormonal activity, genetic darnage has been proposed as an important factor in oestrogen-mediated carcinogenesis. However, as short-term tests for oestrogens usually fail to show DNA mutations, lesions other than dassie nuclear DNA ...
