cryo-EM reveals the properties of distinct conformations occupied during activation of the lipid scramblase nhTMEM16 and provides new insights into its interactions with the lipid environment.

UBIAD1 mediates a unique geranylgeranyl pyrophosphate-sensing mechanism that when disrupted, inhibits degradation of HMG CoA reductase and triggers overproduction of corneal cholesterol that characterizes the eye disease Schnyder Corneal Dystrophy.

Multiple biochemical assays show that the topology of CCR5 and possibly other GPCRs may be inverted by ceramide or other sphingolipids through the process of regulated alternative translocation.

Nramp-family transporters adapt a common fold to a novel mechanism in which the spatial and temporal separation of like-charge transition metal and proton co-substrates circumvents the expected electrostatic repulsion.

Analysis of the Escherichia coli DnaB helicase•bacteriophage λ helicase loader (λP) complex provides insights into helicase opening, delivery to the origin and ssDNA entry, and closing in preparation for translocation.

Photoswitchable ceramides containing an azobenzene photoswitch behave as light-controllable substrates for both sphingomyelin synthase and glucosylceramide synthase.

In vivo inhibition of SUMO activating E1-enzymes by pyrophosphate reveals a mode of integrating metabolism and stress tolerance that is conserved across kingdoms.

With the removal of confounding artifacts, ribosome profiling can yield insight into the mechanism of protein synthesis in bacteria at high resolution.

Construction of a first atomic model for an intact bacterial ATP synthase allows for a structural understanding of the roles of individual amino acids in the mechanism of ATP synthesis.

Researchers are undertaking a systematic assessment of the reproducibility of biomedical science in Brazil.
