The structure of the carbohydrate backbone of the LPS from Shewanella spp. MR-4

The rough type lipopolysaccharide isolated from Shewanella spp. strain MR-4 was analyzed using NMR, mass spectroscopy, and chemical methods. Two structural variants have been found, both contained 8-amino-3,8-dideoxy-d-manno-octulosonic acid and lacked l-glycero-d-manno-heptose. A minor variant of the LPS contained phosphoramide substituent.
