Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

The FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.

Dimerization of human PARP15 is required for NAD+ binding and automodification

The FEBS Journal, EarlyView.
This study provides an integrated structural model of human PARP15. Biophysical, enzymatic, and cell‐based analyses identify the dimer as the active oligomeric state capable of binding the substrate NAD+. A co‐crystal structure with a non‐hydrolyzable substrate analog BAD reveals the molecular basis for the dimerization requirement.

Lender‐Affiliated Analysts and Syndicated Loans

Financial Management, EarlyView.
ABSTRACT Loans to borrowers covered by affiliated analysts have lower spreads. This effect is driven mostly by affiliated analysts sharing information with, rather than demanding information from, lending arms. Exploiting plausibly exogenous changes in brokerage affiliations, we find that the results are likely to be causal.

Gender Tokenism in Corporate Boardrooms in Europe

Gender, Work &Organization, EarlyView.
ABSTRACT We examine the tension between the diversity spillover and tokenism hypotheses using a novel and extensive dataset of nearly 6 million private corporations across 29 European countries from 1986 to 2020. The diversity spillover hypothesis suggests that appointing women to supervisory roles facilitates greater female representation in executive

Extended Reality in Endodontics: A Review of Current Applications and Future Potential

International Endodontic Journal, EarlyView.
ABSTRACT Background Extended reality (XR) technologies, encompassing augmented reality (AR), virtual reality (VR), and mixed reality (MR), are increasingly used in endodontic education and practice. A gap exists regarding understanding of XR's applications and limitations among endodontic educators and practitioners.
