Antioxidant Defense in the Toughest Animals on the Earth: Its Contribution to the Extreme Resistance of Tardigrades

by Keith CowingSeptember 23, 2024September 23, 2024

Tardigrades are unique among animals in their resistance to dehydration, mainly due to anhydrobiosis and tun formation. They are also very resistant to high-energy radiation, low and high temperatures, low […]

Space Station Study Models How Dust And Humidity Create Mold Problems For Astronauts

by Keith CowingSeptember 18, 2024September 18, 2024

Mold can survive the harshest of environments, so to stop harmful spores from growing on future space stations, a new study suggests a novel way to prevent its spread.

Open and closed conformations of rcPEPCK along the reaction coordinate. Superposition of the open and closed structures (N-terminal domain residues 3-250) of rcPEPCK, indicating conformational changes of A) the global structure and B) the active site. Holo rcPEPCK (open) is shown in steel blue (PDB 2QEW), and its Ω-loop in light grey, R-loop in coral, and P loop in lilac. Oxalate- (enol-pyruvate intermediate mimic) GTP bound rcPEPCK (closed) is shown in gold (PDB 3DT2) and its Ω-loop in grey, R-loop in firebrick red, and P-loop in purple. Oxalate9 and GTP are shown bound to the active site and atoms are colored by type (red – oxygen, blue – nitrogen, green – carbon, purple – phosphorous, pink – manganese). -- biorxiv.org

A Structural Perspective on the Temperature-dependent Activity of Enzymes

by Keith CowingSeptember 3, 2024September 2, 2024

Enzymes are biomolecular catalysts whose activity varies with temperature. Unlike for small-molecule catalysts, the structural ensembles of enzymes can vary substantially with temperature, and it is in general unclear how […]

When com162 pared with their closest terrestrial relatives all ISS species have different numbers of 163 unique annotations (Fig. 3a), which corresponds to their ANI (the higher the ANI, the fewer unique annotations) -- biorxiv.org
