Orthophosphate requirement for the formation of phosphoenolpyruvate from pyruvate by enzyme preparations from photosynthetic bacteria.
The formation of phosphoenolpyruvate from pyruvate and adenosine 5'-triphosphate by enzymes from photosynthetic bacteria required inorganic phosphate, thus indicating that these organisms utilize pyruvate, orthophosphate dikinase rather than phosphoenolpyruvate synthase in photosynthesis.
