Export of honeybee prepromelittin in Escherichia coli depends on the membrane potential but does not depend on proteins secA and secY [PDF]

, 1989
Honeybee prepromelittin (70 amino acid residues), the precursor of an eukaryotic secretory protein, and a hybrid protein between prepromelittin and mouse dihydrofolate reductase (257 amino acid residues) were expressed in Escherichia coli and ...

The effect of imipenem and diffusible signaling factors on the secretion of outer membrane vesicles and associated Ax21 proteins in Stenotrophomonas maltophilia [PDF]

, 2015
Outer membrane vesicles (OMVs) are small nanoscale structures that are secreted by bacteria and that can carry nucleic acids, proteins, and small metabolites. They can mediate intracellular communication and play a role in virulence.

Exercise serum promotes DNA damage repair and remodels gene expression in colon cancer cells

International Journal of Cancer, EarlyView.
What's New? Exercise releases bioactive molecules into the bloodstream that can directly slow cancer cell growth. In colon cancer, this may help limit disease progression. Here, using colon cancer cells, the authors investigated the effects of exercise‐conditioned human serum on DNA repair mechanisms. Notably, acute exercise in humans elicited systemic

The endoplasmic reticulum in plant immunity and cell death [PDF]

, 2012
The endoplasmic reticulum (ER) is a highly dynamic organelle in eukaryotic cells and a major production site of proteins destined for vacuoles, the plasma membrane, or apoplast in plants.

Diagnostic performance of urinary adipsin as a screening biomarker for pre‐eclampsia

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective This study evaluated the diagnostic performance of urinary adipsin as a potential biomarker for pre‐eclampsia screening in a low‐resource setting. Methods A case–control study was conducted involving 150 pregnant women classified into three groups: 50 healthy pregnancies, 50 high‐risk pregnancies without pre‐eclampsia, and 50 ...

Septal secretion of protein A in Staphylococcus aureus requires SecA and lipoteichoic acid synthesis

eLife, 2018
Surface proteins of Staphylococcus aureus are secreted across septal membranes for assembly into the bacterial cross-wall. This localized secretion requires the YSIRK/GXXS motif signal peptide, however the mechanisms supporting precursor trafficking are ...

Preprotein mature domains contain translocase targeting signals that are essential for secretion [PDF]

, 2017
Secretory proteins are only temporary cytoplasmic residents. They are typically synthesized as preproteins, carrying signal peptides N-terminally fused to their mature domains. In bacteria secretion largely occurs posttranslationally through the membrane-

Regulation of the Escherichia coli secA gene by protein secretion defects: analysis of secA, secB, secD, and secY mutants [PDF]

Journal of Bacteriology, 1988
SecA protein synthesis levels were elevated 10- to 20-fold when protein secretion was blocked in secA, secD, and secY mutants or in a malE-lacZ fusion-containing strain but not in a secB null mutant. An active secB gene product was not required to derepress secA, since SecA levels were elevated during protein export blocks in secB secY and secB malE ...
