  • n. A polymer of glycan and peptides found in bacterial cell walls

peptide + glycan, a polysaccharide.


  • Cluster III genes, which are positively regulated by CbfA-CTD, are enriched in GO terms representing functions that support bacterial food uptake and degradation, such as peptidoglycan degradation (e.g., lysozyme activity) and proteolysis.

  • In the discussion, the authors present additional evidence that supports their finding, including, but not limited to: (a) the inability to detect cytochromes within the methanogens; (b) the fact that the cell walls of methanogens do not contain peptidoglycan; (c) the 23S rRNA sequence is also divergent from typical bacteria.

  • They work by inhibiting cross-linkage between the linear peptidoglycan polymer chains that make up blocks of the cell wall.

  • Normal flagella need a P-ring to span the cell wall made of peptidoglycan and an L-ring to span the outer membrane.

  • For many species of bacteria, the thick peptidoglycan layer present in gram-positive cell walls is considered a potential barrier to DNA uptake.

    1 Upgrading Traditional Biotechnological Processes

  • The constitutive SrtA catalyzes the covalent binding of the minor ancillary AP2 to peptidoglycan and since its inactivation leads to pilus secretion

  • A second series of modifications enhances the secretion process, by genetically deleting or modifying two key layers of the cellular envelope-known as the S and peptidoglycan layers-allowing fatty acids to more easily escape outside the cell, where their low water solubility causes them to precipitate out of solution, forming a whitish residue on the surface.
