X-ray absorption spectra measured at the Cu K-edge were used to determine the oxidation states and chemical environments of Cu species in the whole-cell and peptidoglycan samples and suggested that Cu(I) was coordinated by amine and thiol ligands.

It is suggested that carboxyl groups provide the major site of metal deposition in the B. subtilis wall, whereas extraction of teichoic acid caused a stoichiometric reduction in levels.
pH dependent charging behavior of isolated cell walls of a gram-positive soil bacterium.
- Biology
- 1995
The cell walls of Gram-positive bacteria are highly porous structures that contain many acidic groups, leading to a pH- and salt-dependent charge, and a binding model, the Langmuir-Freundlich equation, is selected which gives a very close reproduction of the observed charging behavior.
