Bioinformatic and biochemical analysis uncovers novel activity in the 2-ER subfamily of OYEs.

Members of the old yellow enzyme (OYE) family utilize a flavin mononucleotide cofactor to catalyze the asymmetric reduction of activated alkenes. The 2-enoate reductase (2-ER) subfamily are of particular industrial relevance as they can reduce α/β alkenes near electron-withdrawing groups. While the broader OYE family is being extensively explored for biocatalytic applications, oxygen sensitivity and poor expression yields associated with the presence of an Fe/S cluster in 2-ERs have hampered their characterization.

A mirror-image experiment: Sorting carbon nanotubes by L-DNA.

DNA has found increasing applications in molecular engineering, yet its chiral property has rarely been utilized. Here, we report a mirror-image experiment using naturally occurring D-DNA and its enantiomer L-DNA to sort a chiral mixture of single-wall carbon nanotubes (SWCNTs). We find that parity conservation leads to a robust experimental outcome: changing DNA chirality results in handedness inversion of the purified nanotube.

Primordial black holes and their gravitational-wave signatures.

In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain both some of the signals from binary black hole mergers observed in gravitational-wave detectors and an important component of the dark matter in the Universe. Significant progress has been achieved both on the theory side and from the point of view of observations, including new models and more accurate calculations of PBH formation, evolution, clustering, merger rates, as well as new astrophysical and cosmological probes.
