Application

Lithium potassium acetyl phosphate:
  • has been used as a substrate for CpxR (transcription factor) in x-ray crystallography to soak CpxR receiver domain (CpxRRD) crystals to obtain the phosphorylated form
  • may be used as a phosphate (P) donor in a study to screen a wide range of natural and synthetic organic phosphate donors with several enzymes on various hydroxyl?compounds for the improved enzymatic synthesis of phosphate monoesters
  • has been used to set up premixA for in vitro translation reaction

Biochem/physiol Actions

Lithium potassium acetyl phosphate is commonly used as the source for acetyl phosphate. So acetyl phosphate can be used as a suitable alternative to replace inorganic oligophosphates in phosphatase-catalyzed transphosphorylation to reduce inorganic monophosphate by-product formation.
