| This coincidence suggests that the D-amino acids originated in peptidoglycan of bacterial cell walls. |
|
| As in Gram-positive bacteria, the inner membrane of spirochetes is closely associated with the peptidoglycan cell wall. |
|
| It can attach and bind to cell walls and kill a cell by catalyzing the hydrolysis of cell wall peptidoglycan. |
|
| The cell wall, which is relatively porous, consists of many polymer layers of peptidoglycan connected by amino acid bridges. |
|
| For instance, the cell walls of all bacteria contain the chemical peptidoglycan. |
|
| For example, an enzyme called lysozyme splits the sugar chains that are the backbone of peptidoglycan molecules. |
|
| A thin spore membrane and a thick cortex of a peptidoglycan are laid down between the two unit membranes. |
|
| Telavancin inhibits cell wall synthesis by inhibition of peptidoglycan biosynthesis. |
|
| A feed additive for livestock, poultry and fish which comprises bile powder and a bacteria powder containing peptidoglycan. |
|
| The active site of peptidoglycan lysis is disrupted in lactalbumin. |
|
| The cell walls of all eubacteria contain the chemical substance peptidoglycan, whereas the cell walls of archaeans lack this substance. |
|
| Several yet unknown genes participate in glycopeptide resistance, which is characterized by a thickened cell wall, due to altered peptidoglycan turnover. |
|
| For cell wall analysis, extraction and separation of peptidoglycan precursors was performed as described. |
|
| Like other beta-lactam antibiotics, it prevents the bacterial cell wall from forming by interfering with the final stage of peptidoglycan synthesis. |
|
| These enzymes sequentially add several amino acids to the peptidoglycan precursors to form side chains, a structure particular to Gram-positive bacteria. |
|
| Our third objective is to understand the mechanism of action and the regulation of peptidoglycan hydrolases, which are potentially lytic enzymes present in the peptidoglycan polymerization complexes. |
|
| The models of this evolution that we propose to study concern the rearrangements of the peptidoglycan synthetic pathway and the substrate specificity of enzymes involved in its polymerization. |
|
| The main component of the wall is called peptidoglycan, which is the key target of penicillin and other similar antibiotics. |
|
| When peptidoglycan is present from bacteria in platelets, it triggers a reaction cascade which ends in the development of a red color. |
|
| The periplasmic space contained fine filamentous material, which probably represent peptidoglycan layer. |
|
|
|
| Instead, the dye gets trapped in a tight package of sugar-filled polymers, called peptidoglycan, which envelops bacterial cells. |
|
| A complete peptidoglycan molecule is comprised of numerous sugar molecules cross-linked to each other, creating a fencelike structure that encloses the fragile protoplast. |
|
| This particularly clobbers gram-negative cells' outer structures, including the thin layer of peptidoglycan bound to the outer membrane, allowing the purple dye to flush away. |
|
| Bacteria constantly remodel their peptidoglycan cell walls, simultaneously building and breaking down portions of the cell wall as they grow and divide. |
