ATP (Adenosine Triphosphate)
ATP (Adenosine Triphosphate) — The primary energy currency of cells, providing the phosphate group transferred by kinases in signal transduction cascades involving peptide receptors.
What Is ATP?
Adenosine triphosphate (ATP) is the universal energy currency of cells. In peptide research, ATP is relevant as the energy source for ribosomal peptide translation, as a phosphate donor for kinase-mediated phosphorylation of peptide substrates, and as a readout in cell viability assays (CellTiter-Glo) used to assess peptide cytotoxicity.
Peptide Research Connections
- Cell viability: ATP luminescence assay (CellTiter-Glo) measures metabolically active cells after peptide treatment
- Kinase assays: ATP-competitive peptide inhibitors of kinases (kinase substrate peptides)
- Ubiquitin activation: E1 enzyme uses ATP to activate ubiquitin for conjugation
