Protein engineering of a reversibly switchable fluorescent protein enables post-hoc reversible and repeatable marking of elevated calcium concentrations using blue light.

Methods that use puromycin to localize active translation do not actually detect the site of translation.

Although puromycin staining is often used to examine subcellular translation, puromycin-labeled proteins are rapidly released from ribosomes even in the presence of elongation inhibitors, which may confound translation site localization.

Endothelial Differentiation Factor 1 (EDF1) plays a critical role in driving mRNA-specific quality control and global transcriptional responses in response to ribosome collisions.

In starving yeast exposed to thermal stress, a transient drop in intracellular pH helps to trigger the heat shock response.

The pyruvate kinase contained in the apicoplast organelle of malaria parasites makes the nucleotide triphosphates required for several processes including transcription of the organellar genome.

Upon deletion of threonine deaminases, biosynthesis of isoleucine is rescued by two promiscuous reactions, one emerges under aerobic conditions and the other is naturally active under anaerobic conditions.

Mitochondrial pyruvate transport is required for brown fat thermogenesis.

Study of TbAQP2 adaptations and substrate interactions shows how this aquaglyceroporin enables cellular entry of large antimicrobial agents in Trypanosoma brucei.

Mitochondrial fatty acid synthesis is best known for producing lipoic acid, however, longer acyl chain products regulate mitochondrial electron transport chain assembly, oxidative TCA cycle metabolism, and skeletal myoblast differentiation.
