Abstract
A new uridine nucleotide was isolated from Pseudomonas aeruginosa P1-III (Habs serotype 5). On the basis of 13C-n.m.r. and p.m.r. spectroscopy, mass spectrometry, i.r.-absorption spectroscopy and circular dichrometry, the structure of the new compound was unequivocally identified as uridine(5′)-diphospho(1)-2,3-diacetamido-2,3-dideoxy-alpha-D-gl ucopyranuronic acid.
