The paper identifies CCA2 enzymes in Asgard archaea and Heimdallarchaeia, challenging the evolutionary separation between archaeal and eukaryotic CCA-adding enzymes and supporting bacterial gene integration prior to eukaryogenesis.

The paper analyzes and characterizes mitochondrial tRNAs in nematodes and arachnids, revealing structural deviations and editing events not captured by genome-based predictions.

The paper identifies a beta-turn element in the Romanomermis culicivorax tRNA nucleotidyltransferase that enables full CCA-adding activity on armless tRNAs when transplanted into the human enzyme.
