Abstract
Pyridapeptide A (1), a cyclohexapeptide containing hexahydropyridazine-3-carboxylic acid (HPDA), 5-hydroxytetrahydropyridazine-3-carboxylic acid (γ-OH-TPDA), and (2S,3R,4E,6E)-2-amino-3-hydroxy-8-methylnona-4,6-dienoic acid residues, and its four glycopeptides, pyridapeptides B-E (2-5, respectively), were isolated from the fermentation broth of the marine sponge-derived Streptomyces sp. OUCMDZ-4539. Their structures were determined on the basis of spectroscopic analysis and chemical methods. Pyridapeptides B-E have one or more 2,3,6-trideoxyhexose sugar units glycosylated at the γ-OH-TPDA residue. The biosynthetic pathways were proposed on the basis of gene cluster analysis. Compounds 4 and 5, containing four sugar groups, displayed significant antiproliferative activity against five human cancer cell lines (PC9, MKN45, HepG2, HCT-116, and K562).

Acinetobacter baumannii K11 and K83 capsular polysaccharides have the same 6-deoxy-l-talose-containing pentasaccharide K units but different linkages between the K units. Int J Biol Macromol 2017; 103:648-655. [PMID: 28528003 DOI: 10.1016/j.ijbiomac.2017.05.082] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2017] [Revised: 04/18/2017] [Accepted: 05/15/2017] [Indexed: 12/18/2022]
Abstract
Acinetobacter baumannii produces a variety of capsular polysaccharides (CPS) via genes located at the chromosomal K locus and some KL gene clusters include genes for the synthesis of specific sugars. The structures of K11 and K83 CPS produced by isolates LUH5545 and LUH5538, which carry related KL11a and KL83 gene clusters, respectively, were established by sugar analysis and one- and two-dimensional 1H and 13C NMR spectroscopy. Both CPS contain l-rhamnose (l-Rha) and 6-deoxy-l-talose (l-6dTal), and both KL gene clusters include genes for dTDP-l-Rhap synthesis and a tle (talose epimerase) gene encoding an epimerase that converts dTDP-l-Rhap to dTDP-l-6dTalp. The K11 and K83 repeat units are the same pentasaccharide, consisting of d-glucose, l-Rha, l-6dTal, and N-acetyl-d-glucosamine, except that l-6dTal is 2-O-acetylated in K83. However, the K units are linked differently, with l-Rha in the main chain in K11, but as a side-branch in K83. KL11 and KL83 encode unrelated Wzy polymerases that link the K units together and different acetyltransferases, though only Atr8 from KL83 is active. The substrate specificity of each Wzy polymerase was assigned, and the functions of all glycosyltransferases were predicted. The CPS structures produced by three closely related K loci, KL29, KL105 and KL106, were also predicted.

Abstract
dTDP-L-rhamnose (dTDP-Rha)-synthesizing dTDP-6-deoxy-L-lyxo-4-hexulose reductase (4-KR) and dTDP-Rha 4-epimerase were characterized from Burkholderia thailandensis E264 by utilizing rmlD(Bth) (BTH_I1472) and wbiB(Bth) (BTH_I1476), respectively. Incubation of the recombinant WbiB(Bth) with RmlA/RmlB/RmlC/Tal, which has previously been shown to generate dTDP-6-deoxy-L-talose (dTDP-6dTal) from α-D-glucose-1-phosphate, dTTP, and NADPH, produced dTDP-Rha. (1)H NMR measurements confirmed that both RmlA/RmlB/RmlC/Tal/WbiB(Bth) and RmlA/RmlB/RmlC/RmlD produced dTDP-Rha. WbiB(Bth) alone produced dTDP-Rha when incubated with dTDP-6dTal. This is the first report to demonstrate epimerase activity interconverting between dTDP-Rha and dTDP-6dTal.
