This study shows that Lgt is essential for membrane and flagellar integrity in H. pylori, and that revertant cells can overcome this stress through gene expression changes.

The paper analyzes Lgt homologues across bacterial pathogens to determine functional diversity and catalytic mechanisms, identifying a conserved motif and substrate specificity differences.

This study shows that cephalosporin resistance in C. difficile is due to inhibition of D,D-carboxypeptidases, not L,D-transpeptidases, and highlights the plasticity of PG biosynthesis.
