Ribosomes and chromosomal DNA fibres could be discerned within the cytoplasm, and gram-positive and gram-negative bacteria could be distinguished by their cell envelope profiles. The former possessed an amorphous, electron dense wall above the plasma membrane,

Biophysical and Biochemical Studies on the Fine Structure of the Sacculi from , and ,ride chains bearing peptide side chains for crosslinking — are well known for a long time (for review see e.g. Schleifer and Kandler, 1972; Labischinski et al., 1985). However, these data gave only rough ideas how the real giant macromolecule murein (synonym: peptidoglycan) is organized to fulfill i

HPLC and 252Cf Plasma Desorption-Mass Spectrometry of Muropeptides Isolated from E. Coli non-volatile compounds like peptides, proteins, glycopeptides, oligosaccharides and oligonucleotides have been developed. The most important mass spectrometric techniques for these classes of compounds proved to be .Cf plasma desorption-(PD-MS), fast atom bombardment-(FAB-MS), matrix assisted laser

Investigations on Structure and Biosynthesis of Cyanelle Murein from , is now generally accepted (Margulis, 1981). However, examples for intermediary or side line forms in this long-lasting and presumably still ongoing process that e. g. combine the function and genetic complexity of an organelle with the distinct prokaryotic structural feature of the peptidoglycan wa

New Methods in Electron Microscopy Help Elucidate the Structure of the Murein Sacculus and the Distrurs, to determine cellular shape and form, to distinguish gram-negative cultures from gram-positive ones, and to detect the position of envelope adornments (e.g., flagella and capsules). These characteristics could usually be determined by light microscopy and it was not until the early 1950s that m
