This study identifies two D-loop resolution systems in bacteria, YraN/ComM and CoiA/RadA, that work together to process the transformation D-loop during natural genetic transformation.

The paper uses cryo-EM and simulations to reveal how LptM and LptY facilitate LPS transport by modulating LptD conformational dynamics in the translocon complex.

This study shows that competence-induced expression of RecA and RadA in Streptococcus pneumoniae enhances tolerance to genotoxic stress, highlighting competence as a stress-sensing mechanism.

The paper identifies aRNase J, a 5’-3’ exoribonuclease in Archaea, as part of a complex with ASH-Ski2 helicase and the RNA exosome, suggesting its role in RNA surveillance and translation.
