Abstract
A new inositol derivative could be isolated from the Archaeum Pyrococcus woesei and identified as di-myo-inositol-1,1'-phosphate by 1H, 31P NMR spectroscopy, mass spectrometry and thin layer chromatography. In P. woesei, this inositol phosphate represents the dominant counterion of K+ which ranges from 500 to 600 mM. The role of the potassium salt of di-myo-inositol-1,1'-phosphate as thermostabilizer is discussed.
摘要
一种新的肌醇衍生物可从嗜热栖热菌中分离出来，并通过1H、31P核磁共振光谱、质谱和薄层色谱法鉴定为二-肌醇-1,1'-磷酸酯。在嗜热栖热菌中，这种肌醇磷酸酯是钾离子（浓度范围为500至600 mM）的主要抗衡离子。文中讨论了二-肌醇-1,1'-磷酸钾盐作为热稳定剂的作用。
