Structural insights into thyroid hormone transporter MCT8

open access: yesNature Communications
Thyroid hormones (THs), including T4 (3,5,3′,5′-tetraiodo-L-thyronine) and T3 (3,5,3′-triiodo-L-thyronine), play critical roles in regulating tissue development and basal metabolism.

Structural mechanisms of pump assembly and drug transport in the AcrAB–TolC efflux system

open access: yeseLife
Tripartite multidrug efflux pumps that span the cell envelope are essential for antibiotic resistance in Gram-negative bacteria. Here, we report cryo-EM structures of two endogenous efflux complexes from Escherichia coli: a TolC–YbjP subcomplex at 3.56 Å

Membrane structure and dynamics

open access: yesCurrent Opinion in Cell Biology, 1989
Research into membrane structure and dynamics has been actively pursued for over live decades by physicists, chemists, biologists and biophysicists, of both a practical and a theoretical persuasion, yet there is still a wealth of new information being produced.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural mechanism of bacteriophage lambda tail’s interaction with the bacterial receptor

open access: yesNature Communications
Bacteriophage infection, a pivotal process in microbiology, initiates with the phage’s tail recognizing and binding to the bacterial cell surface, which then mediates the injection of viral DNA.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Integral hollow fiber membrane with chemical cross-linking for pressure retarded osmosis operated in the orientation of active layer facing feed solution

open access: yes, 2017
Pressure retarded osmosis (PRO) is an innovative technique to yield osmotic energy. Nevertheless, the PRO performance is exacerbated by the severe membrane fouling occurring within the porous support.
