Presence and expression of hydrogenase specific C-terminal endopeptidases in cyanobacteria [PDF]

BMC Microbiology, 2003
Background Hydrogenases catalyze the simplest of all chemical reactions: the reduction of protons to molecular hydrogen or vice versa. Cyanobacteria can express an uptake, a bidirectional or both NiFe-hydrogenases.

Control of the Pseudomonas aeruginosa LbcA•CtpA proteolytic complex and its substrates [PDF]

Journal of Bacteriology
Pseudomonas 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.

Localization and Dynamics of the Cell Shape-Determining Csd2 Protein Complex in H. pylori [PDF]

Cells
Approximately 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

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.

A Cell Wall Hydrolase MepH Is Negatively Regulated by Proteolysis Involving Prc and NlpI in Escherichia coli

Frontiers in Microbiology, 2022
Cell wall assembly of Gram-negative bacteria requires DD-endopeptidase activity that cleaves peptidoglycan (PG) crosslinks in addition to PG synthetic activity, and the activity of DD-endopeptidases needs to be tightly regulated to maintain cell wall ...

Distinct Amino Acid Availability-Dependent Regulatory Mechanisms of MepS and MepM Levels in Escherichia coli

Frontiers in Microbiology, 2021
Peptidoglycan (PG) hydrolases play important roles in various aspects of bacterial physiology, including cytokinesis, PG synthesis, quality control of PG, PG recycling, and antibiotic resistance. However, the regulatory mechanisms of their expression are
