Abstract
Cell-free extracts of Methanobacterium thermoautotrophicum were found to catalyze ATP synthesis from an endogeneous substrate. Synthesis was stimulated under hydrogen atmosphere and inhibited by KCL (Ki=150 mM). Comparison of the properties of a number of cell constituents showed the endogeneous substrate to be 2,3-diphosphoglycerate. The compound is converted into 3-phosphoglycerate, and via 2-phosphoglycerate and phosphoenolpyruvate into pyruvate, at which the latter reaction is linked with ATP synthesis.
