Molecular basis for the production of cyclic peptides by plant asparaginyl endopeptidases
Nature Communications, 2018 Asparaginyl endopeptidases (AEPs) are plant proteases that can also function as ligases, catalyzing the production of cyclic plant peptides. Here, the authors identify structural features that govern AEP ligase activity, providing insights to aid the ...

Genetic Evidence for Distinct Functions of Peptidoglycan Endopeptidases in Escherichia coli
Frontiers in Microbiology, 2020 Peptidoglycan (PG) is an essential component of the bacterial exoskeleton that plays a pivotal role in the maintenance of cell shape and resistance to cell lysis under high turgor pressures.

Localization and Dynamics of the Cell Shape-Determining Csd2 Protein Complex in H. pylori [PDF]
CellsApproximately half of the world population is infected with the human pathogen Helicobacter pylori, which causes gastric inflammation, chronic gastritis, or peptide ulceration. A significant factor in the colonization of the upper digestive system is the

Control of the Pseudomonas aeruginosa LbcA•CtpA proteolytic complex and its substrates [PDF]
Journal of BacteriologyPseudomonas aeruginosa is a highly adaptable bacterial pathogen with a resilient cell envelope. This envelope must be elongated as cells grow, which requires coordinated biosynthesis of the inner and outer membranes and the peptidoglycan cell wall.

Structural basis for recruitment of peptidoglycan endopeptidase MepS by lipoprotein NlpI [PDF]
Nature CommunicationsPeptidoglycan (PG) sacculi surround the cytoplasmic membrane, maintaining cell integrity by withstanding internal turgor pressure. During cell growth, PG endopeptidases cleave the crosslinks of the fully closed sacculi, allowing for the incorporation of ...

A Chemical and Enzymatic Approach to Study Site-Specific Sumoylation. [PDF]
, 2015 A variety of cellular pathways are regulated by protein modifications with ubiquitin-family proteins. SUMO, the Small Ubiquitin-like MOdifier, is covalently attached to lysine on target proteins via a cascade reaction catalyzed by E1, E2, and E3 enzymes.
