Acute Inhalation Exposure to Ultrafine Carbon Black Alters Mitochondrial Substrate Utilization in the Heart

Environmental Toxicology, EarlyView.
ABSTRACT A majority of deaths associated with air pollution are attributed to cardiovascular and heart diseases. Carbon black that represents the carbon core of particulate matter, a major component of air pollution, has been shown to result in cardiac mitochondrial dysfunction.

Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

The FEBS Journal, EarlyView.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.
