Carboxypeptidase activity drives L,D-transpeptidase essentiality during vegetative growth and sporulation in Clostridioides difficile

Kevin W. Bollinger, Ute Müh, Paige B Brannen…·Craig D. Ellermeier

This paper identifies DD-CPases as the source of tetrapeptides for LDTs in C. difficile and shows that LDTs are essential due to high DD-CPase activity, not for divisome/elongasome function.

Bacterial cell surface nanoenvironment requires a specialized chaperone to activate a peptidoglycan biosynthetic enzyme

Thomas Delerue, Taylor B. Updegrove, Sylvia Chareyre…·Kumaran S. Ramamurthi

This study identifies SpoVK as a chaperone that activates MurG during spore surface assembly in Bacillus subtilis, highlighting the need for specialized chaperones in specific nanoenvironments.

Identification of a new family of peptidoglycan transpeptidases reveals atypical crosslinking is essential for viability in Clostridioides difficile

Kevin W. Bollinger, Ute Müh, Karl L. Ocius…·Craig D. Ellermeier

This study identifies a new family of LDTs in C. difficile that catalyze 3-3 peptidoglycan crosslinking, essential for viability and distinct from previously known YkuD domain LDTs.
