Tl. Arsenault et al., SMITH-DEGRADATIVE STUDIES ON THE POLYSACCHARIDE PORTION OF A-BAND LIPOPOLYSACCHARIDE FROM A MUTANT (AK1401) OF PSEUDOMONAS-AERUGINOSA STRAIN PAO1, Canadian journal of chemistry, 72(5), 1994, pp. 1376-1382
pha-D-Rhap-(1-->3)-O-alpha-D-Rhap-(1-->2)-glycerol (5) was the major c
omponent derived by way of Smith degradation of A-band polysaccharide
(a D-rhamnan isolated from a mutant, AK1401, of Pseudomonas aeruginosa
strain PAO1). The structure has been verified by an unambiguous synth
esis of 5. Based on mass spectrometric evidence, tyl-O-Ribp-(1-->3)-O-
alpha-D-Rhap-(1-->2)-glycerol is considered to be one of the minor com
ponents. The Smith degradation of A-band polysaccharide and the synthe
sis of 5 are reported.
