Current Work

Bacteria have a highly complex cell envelope. The essential peptidoglycan sacculus is a mesh-like cell envelope layer required to protect the cell from rupture due to its turgor and to maintain cell shape. The biosynthetic pathway of peptidoglycan synthesis is the target of our most successful antimicrobials, the beta-lactams and glycopeptides. During growth and cell division the sacculus surface is enlarged by the combined actions of peptidoglycan synthases (penicillin-binding proteins, PBPs) and hydrolases (lytic transglycosylases, amidases and endopeptidases). According to a current model, peptidoglycan enzymes and cell morphogenesis proteins form dynamic multi-enzyme complexes which are regulated by cytoskeletal elements. Escherichia coli and presumably other Gram-negative bacteria also regulate peptidoglycan growth by outer membrane-anchored lipoproteins that specifically stimulate their cognate, inner membrane-anchored synthase. 

Our research aims to decipher the molecular mechanisms of peptidoglycan growth in the model bacterium Escherichia coli and other Gram-negative and Gram-positive bacteria. We study the activities and interactions of peptidoglycan enzymes and aim to identify novel members of the pathway. We also investigate the spatiotemporal regulation of peptidoglycan growth and the mechanisms of cell shape generation in various species. Finally, we determine the peptidoglycan fine structure (muropeptide composition) and cell wall architecture in Gram-positive and Gram-negative bacteria.
