title: Arrangement of glycan chains in the sacculus of Escherichia coli.
abstract: A novel of Escherichia coli endopeptidase was used for a selective partial hydrolysis of the peptide bridges which interlink the glycan chains in E. coli sacculi. The loosening of the murein network revealed, in the electron microscope, a preferential orientation of the glycan chains, more or less perpendicular to the length axis of the cell. Control incubations with E. coli transglycosylase or egg-white lysozyme did not leave ordered structures behind.
