In August 2018, long, narrow clouds stood out against the backdrop of marine clouds blanketing much of the North Pacific Ocean. Known as ship tracks, the distinctive clouds form when water vapor condenses around the tiny particles emitted by ships in their exhaust. Ship tracks typically form in areas where thin, low-lying stratus and cumulus clouds are present.

Conservation of coactivator engagement mechanism enables small-molecule allosteric modulators [Biochemistry]
Transcriptional coactivators are a molecular recognition marvel because a single domain within these proteins, the activator binding domain or ABD, interacts with multiple compositionally diverse transcriptional activators. Also remarkable is the structural diversity among ABDs, which range from conformationally dynamic helical motifs to those with a stable core such as…

Acid-responsive activity of the Helicobacter pylori metalloregulator NikR [Biochemistry]
Helicobacter pylori is a human pathogen that infects the stomach, where it experiences variable pH. To survive the acidic gastric conditions, H. pylori produces large quantities of urease, a nickel enzyme that hydrolyzes urea to ammonia, which neutralizes the local environment. One of the regulators of urease expression in H….

Recycling of Golgi glycosyltransferases requires direct binding to coatomer [Cell Biology]
The glycosyltransferases of the mammalian Golgi complex must recycle between the stacked cisternae of that organelle to maintain their proper steady-state localization. This trafficking is mediated by COPI-coated vesicles, but how the glycosyltransferases are incorporated into these transport vesicles is poorly understood. Here we show that the N-terminal cytoplasmic tails…
