title: Threo-beta-hydroxyornithine: a natural constituent of the peptidoglycan of Corynebacterium species Co 112.
abstract: Peptidoglycan of Corynebacterium species Co 112 (DSM 20606) exhibits an unknown amino acid. The amino acid was isolated from cell wall hydrolysates and identified as threo-beta-hydroxyornithine. This amino acid is found in the interpeptide bridge of the peptidoglycan of Corynebacterium sp. Co 112. The primary structure of this peptidoglycan is rather similar to that of Microbacterium liquefaciens. The only difference is the replacement of ornithine by threo-beta-hydroxyornithine. The mode of linkage of threo-beta-hydroxyornithine indicates that it is present as D-isomer.
