Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases. [PDF]

Proteins
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Plant Responses to Anomalous Heat and Drought Events in the Sonoran Desert. [PDF]

Glob Chang Biol
What are the impacts of region‐wide heat and drought events on desert vegetation? This multi‐scale assessment shows that columnar cacti and succulent trees show acute plant stress across the Sonoran Desert. The expected increased frequency of heat and drought events will likely have landscape‐wide impacts that could fundamentally reshape populations of
