Inclusion complexes of V-amylose with undecanoic acid and dodecanol at atomic resolution: X-ray structures with cycloamylose containing 26 d-glucoses (cyclohexaicosaose) as host

Autor: Wolfram Saenger, Isabel Usón, George M. Sheldrick, Katrin Gessler, Olaf Nimz

Publikováno v: Carbohydrate Research. 339:1427-1437

Crystal structures are reported of cycloamylose containing 26 D-glucose residues (CA26, cyclohexaicosaose, C156H260O130) in complexes with undecanoic acid (CA26 x 2C10H21COOH x 34.95 H2O, orthorhombic P2(1)2(1)2(1), one CA26 and two bound undecanoic

X-ray structure of the cyclomaltohexaicosaose triiodide inclusion complex provides a model for amylose–iodine at atomic resolution

Cyclomaltohexaicosaose (CA26) is folded into two 1(2)/(3) turns long V-helices that are oriented antiparallel. Crystals of complexes of CA26 with NH(4)I(3) and Ba(I(3))(2) are brown and X-ray analyses show that I(3)(-) units are located in the approx

V-Amylose at atomic resolution: X-ray structure of a cycloamylose with 26 glucose residues (cyclomaltohexaicosaose)

Autor: Wolfram Saenger, Isabel Usón, George M. Sheldrick, Norbert Krauss, Shigetaka Okada, Steven M. Smith, Katrin Gessler, Takeshi Takaha

The amylose fraction of starch occurs in double-helical A- and B-amyloses and the single-helical V-amylose. The latter contains a channel-like central cavity that is able to include molecules, “iodine’s blue” being the best-known representative

Spannungsinduzierte 'Band-Flips' in Cyclodecaamylose und höheren Homologen

Autor: Haruyo Sanbe, Joël Jacob, Daniel Hoffmann, Takeshi Takaha, Kyoko Koizumi, Katrin Geßler, Wolfram Saenger, Steven M. Smith

Publikováno v: Angewandte Chemie. 110:626-629

Groser, aber nicht geraumiger als die kleineren Cyclodextrine sind homologe Cycloamylosen (CAs) mit ≥ 10 Glucoseeinheiten. Durch Verdrehung von je zwei Glucoseresten einer Molekulhalfte um 90° ( „Knick”) bzw. 180° ( „Band-Flip”) gegenuber

ChemInform Abstract: Structures of the Common Cyclodextrins and Their Larger Analogues - Beyond the Doughnut

Autor: Thomas Steiner, Haruyo Sanbe, Takeshi Takaha, Wolfram Saenger, Kyoko Koizumi, Katrin Gessler, Steven M. Smith, Daniel Hoffmann, Joël Jacob

Publikováno v: ChemInform. 29

If the amylose fraction of starch is degraded by glucosyltransferases, one or several turns of the amylose helix are hydrolyzed off and their ends are joined together, thereby producing cyclic oligosaccharides called cyclodextrins (CDs) or cycloamylo
