Analysis of Polycaprolactone Microfibers as Biofilm Carriers for Biotechnologically Relevant Bacteria

, 2018
Polymeric electrospun fibers are becoming popular in microbial biotechnology because of their exceptional physicochemical characteristics, biodegradability, surface-to-volume ratio, and compatibility with biological systems, which give them a great ...

Molecular characterisation of recombinant human pyroglutamyl peptidase (type I) [PDF]

, 2005
Pyroglutamyl Peptidase I (PAP1, EC 3.4.19.3) hydrolytically cleaves pyroglutamic acid (pGlu) from the N-terminal of most pGlu-peptides. In higher organisms Thyrothropin Releasing Hormone is a notable biologically active substrate of PAP1. The sequence of

Bioactivity of tempe by inhibiting adhesion of ETEC to intestinal cells, as influenced by fermentation substrates and starter pure cultures

, 2010
Soya bean tempe is known for its bioactivity in reducing the severity of diarrhoea in piglets. This bioactivity is caused by an inhibition of the adhesion of enterotoxigenic Escherichia coli (ETEC) to intestinal cells.

Induced conformational changes activate the peptidoglycan synthase PBP1B [PDF]

, 2018
International audienceBacteria surround their cytoplasmic membrane with an essential, stress-bearing peptidoglycan (PG) layer consisting of glycan chains linked by short peptides into a mesh-like structure.

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis

Advanced Science, EarlyView.
In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.

New insights into the journey of lipoproteins in the cell envelope of Escherichia coli : disorder matters

, 2021
The cell envelope is essential for bacterial survival, as it forms a protective barrier that shelters the cell from its environment. This envelope consists of an outer and an inner membrane; both membranes are separated by the periplasm. In the periplasm,

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

It's a trap : new findings into the role of outer membrane proteins in the Rcs stress response system of Escherichia coli

, 2022
The cell envelope of Gram-negative bacteria is essential for their survival. It serves as their initial line of defense as well as a physical barrier between the cell and its surrounding environment.

Lilrb4a Suppression Reprograms Microglia to Mitigate APOE4‐Associated Amyloid Plaques and Cerebral Amyloid Angiopathy in Association With a PPAR‐Linked Pro‐Clearance State

Advanced Science, EarlyView.
Targeting Lilrb4a in Apolipoprotein E4 (APOE4)‐associated Alzheimer's disease (AD) reprograms microglia toward a beneficial, phagocytic state. Genetic deletion or antisense inhibition of Lilrb4a suppresses p‐SHP2/NF‐κB/STAT1 signaling, restores PPAR‐linked lipid and energy metabolism, and reduces amyloid plaque burden and cerebral amyloid angiopathy ...

Secondary water pore formation for proton transport in a ClC exchanger revealed by an atomistic molecular dynamics simulation

, 2008
Several prokaryotic ClC proteins have been demonstrated to function as exchangers that transport both chloride ions and protons simultaneously in opposite directions.
