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.
