Zusammenfassung: | The cyclic pyrophosphate obtained from M. thermoautotrophicum was converted to sn-glycerol 3-phosphate by a stereospecific route. This conversion establishes the structure as cyclic-2,3-diphospho-D-glycerate. The same method was used to determine the cellular content of this metabolite under two conditions: batch culture in a medium containing 2 mM inorganic phosphate and continuous culture with 0.1 mM phosphate in the inflowing medium. The values found were 194 plus or minus 13 and 27.5 plus or minus 1.1 mu mol/g dry weight, respectively. Computer modeling indicated that the pyrophosphate group cannot adopt a staggered conformation. |
