Adaptation of a Fluorogenic RNA to N1‐Methylpseudouridine Nucleoside Chemistry

open access: yesAngewandte Chemie, EarlyView.
Several green‐emitting fluorogenic RNA aptamers were evaluated following the replacement of every uridine by N1‐methylpseudouridine (mΨ). Because this modification impaired the function of most aptamers, a directed evolution strategy combining droplet microfluidics, bioinformatics, and rational design was used to identify an aptamer preserving its ...

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...
