核酸/蛋白质测序技术已广泛应用,但缺乏对复杂多糖进行测序的直接方法。我们在这里提出了一个战略,糖胺聚糖序列,长的线性多糖参与许多生化过程。该方法是基于共价固定和(免疫)化学表征的只有那些大小分离的引物,港口的全长链的原始还原端。使用这种方法,测定了蛋白聚糖bikunin的硫酸软骨素链的糖序列。该方法可以在任何标准的生物化学实验室中进行,并开放研究复杂的糖序列与其他生物分子的相互作用。
Technologies to sequence nucleic acids/proteins are widely available, but straightforward methodologies to sequence complex polysaccharides are lacking. We here put forward a strategy to sequence glycosaminoglycans, long linear polysaccharides involved in many biochemical processes. The method is based on the covalent immobilization and (immuno)chemical characterization of only those size-separated saccharides that harbor the original reducing end of the full-length chain. Using this methodology, the saccharide sequence of the chondroitin sulfate chain of the proteoglycan bikunin was determined. The method can be performed in any standard biochemical lab and opens studies to the interaction of complex saccharide sequences with other biomolecules.
