Popis: The complex of Fe(III) with the peptidoglycan monomer (PGM) was prepared and characterised by chemical and physicochemical methods. The analyses showed that it contains two PGM molecules bonded with five Fe(III) ions. Mossbauer spectroscopy indicates that the iron oxy/hydroxy core has a dimeric or polymeric structure. Differential IR spectroscopy suggests complexation via carbonyl groups and NMR spectroscopy contribution of the carbonyl groups of D-isoglutaminyl, meso-diaminopimeloyl, D-alanyl residues and the carboxyl group of the C-terminal D-alanyl moiety of the peptidoglycan monomer. On the basis of the data obtained the possible structure of the Fe(III) PGM complex was proposed.
