Novel diglycosyldiacylglycerol from the gram-negative bacterium Deleya marina

Biochim Biophys Acta. 1998 Jul 31;1393(1):161-5. doi: 10.1016/s0005-2760(98)00070-8.


A glycosyldiacylglycerol was isolated from the marine bacterium Deleya marina (ATCC 25374). The structure was determined, mainly by spectral data, to be 1, 2-diacyl-3-O-[alpha-2-amino-2-deoxy-glucopyranose-(1-->4)-O-alpha-idu ronopyranuronic acid]-glycerol. This is, to our knowledge, the first isolation of diglycosyldiacylglycerol containing both iduronopyranuronic acid and 2-amino-2-deoxy-glucopyranose from Gram-negative bacteria.
