Abstract

Capsular polysaccharides were recovered from four Acinetobacter baumannii isolates, and the following related structures of oligosaccharide repeating units were established by sugar analyses along with 1D and 2D 1H and 13C NMR spectroscopy: NIPH 60 and LUH5544 (K43) NIPH 601 (K47) The K locus for capsule biosynthesis in the genome sequences available for NIPH 60 and LUH5544, designated KL43, was found to be related to gene clusters KL47 in NIPH 601 and KL88 in LUH5548. The three clusters share most gene content differing in only a small portion that includes an additional glycosyltransferase genes in KL47 and KL88, as well as genes encoding distinct Wzy polymerases that were found to form the same α-d-GlcpNAc-(1 → 6)-α-d-GlcpNAc linkage in K43 and K47.
