| Title | Chemical Analysis of Peptidoglycans from Species of Chromatiaceae and Ectothiorhodospiraceae  | ||
| Abstract | Rigid layer (sodium dodecylsulfate(SDS)-insoluble cell wall) and peptidoglycan fractions were obtained from the Chromatiaceae (Thiocysüs violacea and Chromatium tepidum) and from Ecto-thiorhodospira vacuolata. Chemical composition of rigid layers from all three species indicated the presence of peptidoglycan-bound protein. Qualitative and quantitative composition of isolated peptidoglycan indicate an Aly-type. meso-Diaminopimelic acid was the only diamino acid found. Direct cross-linkage of peptide side-chains was confirmed by separation of respective dipeptides (M-A ; pm-D-Ala) from partial acid hydrolysates of peptidoglycan. GlcN and MurN of the sugar strands are completely N-acetylated. All peptidoglycan fractions contained small amounts of Gly. | ||
