It suggests that the stem domains interact and the catalytic domains have freedom to move from the position observed in the crystal structure.
The function of FtsL and FtsB is not known, but their presence is indispensable for the correct divisome assembly (Gonzalez and Beckwith, 2009 Gonzalez et al. This model extends our understanding of PBP5 function as it suggests how PBP5 can interact with the peptidoglycan layer. PBP3 catalyses the cross-linking of the transported precursors to the septal peptidoglycan (Begg et al., 1990). As the crystal structure of the soluble domain of PBP5 (i.e., lacking the membrane anchor) shows a monomer, we used our experimental data to generate a model of the homo‐dimer. Both approaches indicate that PBP5 exists as a homo‐oligomeric complex, most likely as a homo‐dimer. dimerization of a leucine zipper was used as a proof of principle (Hu et. Inhibition of PBP2 s activity results an increase of the diameter of the new. PBP2 on the other hand is involved in the constriction pr ocess but its function is not essential. In this study, we have analyzed the oligomeric state of PBP5 in detergent and in its native environment, the inner membrane. The function and physical presence of PBP3 is necessary to fully complete cell constriction. aureus can become resistant to methicillin and other -lactam antibiotics through the expression of a. In doing so, it varies the substrates for transpeptidation and plays a key role in maintaining cell shape. Staphylococcus aureus is a major pathogen both within hospitals and in the community.Methicillin, a -lactam antibiotic, acts by inhibiting penicillin-binding proteins (PBPs) that are involved in the synthesis of peptidoglycan, an essential mesh-like polymer that surrounds the cell. Penicillin‐binding protein 5 (PBP5) is a DD‐carboxypeptidase, which cleaves the terminal D‐alanine from the muramyl pentapeptide in the peptidoglycan layer of Escherichia coli and other bacteria.
