The O-chain polysaccharide (OPS) of the lipopolysaccharide of Xanthomonas campestris pv. begoniae GSPB 525 was found to contain L-rhamnose and L-xylose in the ratio 1:0.6. The OPS lacked strict regularity because of nonstoichiometric xylosylation of the main rhamnan chain. Based on methylation analysis, Smith degradation, and 1H and 13C NMR spectroscopy, including COSY, TOCSY, NOESY, and H-detected 1H,13C heteronuclear multiple-quantum coherence (HMQC) experiments, the following structure of the OPS was established: [formula: see text].
野油菜黄单胞菌致病变种秋海棠GSPB 525脂多糖的O-链多糖（OPS）被发现含有比例为1:0.6的L-鼠李糖和L-木糖。由于主鼠李聚糖链的木糖基化非化学计量，该OPS缺乏严格的规律性。基于甲基化分析、史密斯降解以及1H和13C核磁共振光谱，包括COSY、TOCSY、NOESY和氢检测的1H,13C异核多量子相干（HMQC）实验，确定了OPS的以下结构：[化学式：见原文]
