Hexitol nucleic acids are oligonucleotides built up from natural nucleobases and a phosphorylated 1,5-anhydrohexitol backbone. The anhydrohexitol oligonucleotide h(GTGTACAC) was synthesized using phosphoramidite chemistry and standard protecting groups. Crystals of h(GTGTACAC) were obtained at either 279 or 289 K by the hanging-drop vapour-diffusion technique using a 24-matrix screen for nucleic acid fragments. The crystals diffract beyond 2.0 A resolution and belong to the hexagonal space group P6222 (or P6422) with unit-cell parameters a = 36.42 and c = 63.33 A.
己糖醇核酸是由天然核碱基和磷酸化的1,5-脱水己糖醇主链构成的寡核苷酸。使用亚磷酰胺化学方法和标准保护基团合成了脱水己糖醇寡核苷酸h(GTGTACAC)。通过悬滴气相扩散技术,使用针对核酸片段的24种基质筛选,在279 K或289 K下获得了h(GTGTACAC)的晶体。这些晶体的衍射分辨率超过2.0 Å,属于六方空间群P6222(或P6422),晶胞参数a = 36.42 Å,c = 63.33 Å。
