D-Arabinofurans, attached to either a galactofuran or a lipomannan, are the primary constituents of mycobacterial cell wall, forming the unique arabinogalactan (AG) and lipoarabinomannan (LAM), respectively. Emerging data indicate that the arabinans of AG and LAM are distinguished by virtue of the additional presence of linear termini in LAM, which entails(More)
The growing number of Klebsiella pneumoniae infections, commonly acquired in hospitals, has drawn great concern. It has been shown that the K1 and K2 capsular serotypes are the most detrimental strains, particularly to those with diabetes. The K1 cps (capsular polysaccharide) locus in the NTUH-2044 strain of the pyogenic liver abscess (PLA) K. pneumoniae(More)
The mycobacterial D-arabinofuran is a common constituent of both cell wall mycolyl-arabinogalactan (AG) and the associated lipoarabinomannan (LAM), and is thus accorded critical structural and immunological roles. Despite a well-recognized importance, progress in understanding its full structural characteristics beyond the nonreducing terminal motifs has(More)
