  2. Lipid II - Wikipedia

    en.wikipedia.org/wiki/Lipid_II

    Lipid II is a precursor molecule in the synthesis of the cell wall of bacteria. It is a peptidoglycan, which is amphipathic and named for its bactoprenol hydrocarbon chain, which acts as a lipid anchor, embedding itself in the bacterial cell membrane. Lipid II must translocate across the cell membrane to deliver and incorporate its disaccharide ...

  3. Peptidoglycan - Wikipedia

    en.wikipedia.org/wiki/Peptidoglycan

    Peptidoglycan hydrolysis and synthesis are two processes that must occur in order for cells to grow and multiply, a technique carried out in three stages: clipping of current material, insertion of new material, and re-crosslinking of existing material to new material.

  4. Divisome - Wikipedia

    en.wikipedia.org/wiki/Divisome

    Divisome and elongasome complexes responsible for peptidoglycan synthesis during lateral cell-wall growth and division. [1]The divisome is a protein complex in bacteria that is responsible for cell division, constriction of inner and outer membranes during division, and peptidoglycan (PG) synthesis at the division site.

  5. Cell envelope - Wikipedia

    en.wikipedia.org/wiki/Cell_envelope

    The bacterial cell wall differs from that of all other organisms by the presence of peptidoglycan (poly-N-acetylglucosamine and N-acetylmuramic acid), which is located immediately outside of the cytoplasmic membrane. Peptidoglycan is responsible for the rigidity of the bacterial cell wall and for the determination of cell shape. It is ...

  6. N-Acetylglucosamine - Wikipedia

    en.wikipedia.org/wiki/N-Acetylglucosamine

    This layered structure is called peptidoglycan (formerly called murein). GlcNAc is the monomeric unit of the polymer chitin, which forms the exoskeletons of arthropods like insects and crustaceans. It is the main component of the radulas of mollusks, the beaks of cephalopods, and a major component of the cell walls of most fungi.

  7. Undecaprenyl phosphate - Wikipedia

    en.wikipedia.org/wiki/Undecaprenyl_phosphate

    In some situations, UP can also be utilized to carry other cell-wall polysaccharides, but UP is the designated lipid carrier for peptidoglycan. During the process of carrying the peptidoglycan across the cell membrane, N-acetylglucosamine and N-acetylmuramic acid are linked to UP on the cytoplasmic side of the membrane before being carried ...

  8. Periplasm - Wikipedia

    en.wikipedia.org/wiki/Periplasm

    As shown in the figure to the right, the periplasmic space in gram-negative or diderm bacteria is located between the inner and outer membrane of the cell. The periplasm contains peptidoglycan and the membranes that enclose the periplasmic space contain many integral membrane proteins, which can participate in cell signaling.

  9. Peptidoglycan glycosyltransferase - Wikipedia

    en.wikipedia.org/wiki/Peptidoglycan_glycosyl...

    Peptidoglycan glycosyltransferase (EC 2.4.1.129) is an enzyme used in the biosynthesis of peptidoglycan. It transfers a disaccharide-peptide from a donor substrate to synthesize a glycan chain. [1] This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases.
