Abstract:
:During intraperiplasmic growth of Bdellovibrio bacteriovorus on Escherichia coli, the substrate cell peptidoglycan is extensively modified as it is converted to bdelloplast peptidoglycan. The initially lysozyme-sensitive peptidoglycan of E. coli was rapidly converted to a lysozyme-resistant form. The conversion was due to the N-deacetylation of a large portion of the peptidoglycan amino sugars. Chemically acetylating the isolated peptidoglycan restored its sensitivity to lysozyme digestion. However, approximately half of the products of lysozyme digestion exhibited hydrophobic interactions that were shown not to be due to the presence of protein. This suggests that a molecule capable of hydrophobic interactions, other than protein, becomes linked to the bdelloplast peptidoglycan. The data also suggest that much of the Braun lipoprotein is removed from the E. coli peptidoglycan early during bdellovibrio development.
