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.

Two-component systems (TCSs) are the largest family of multi-step signal transduction pathways and valuable sensors for synthetic biology. However, most TCSs remain uncharacterized or difficult to harness for applications. Major challenges are that many TCS output promoters are unknown, subject

We have developed protocols to generate site-specific variants of the histidine-kinase DesK and its cognate response regulator DesR, conducive to trapping different signaling states of the proteins. Co-expression of both partners in E. coli, ensuring an excess of the regulator

Hybrid sensor kinase, which contains a histidine kinase (HK) domain, a receiver domain, and a histidine-containing phosphotransmitter (HPt) domain, conveys signals to its cognate response regulator by means of a His-Asp-His-Asp phosphorelay. We examined the multistep phosphorelay of a recombinant
