KEMPTIDE Chemical Properties,Usage,Production
Uses
Kemptide, phosphate acceptor, is shown to be a basic serine-containing heptapeptide corresponding to a sequence from pig liver pyruvate kinase. This synthetic peptide is a substrate of PKA (cyclic AMP-dependent protein kinase) and is phosphorylated and activated after microinjection into Xenopus oocytes. Exposure of Kemptide to insulin has demonstrated an increase in activation of this agent, which can be inhibited by the catalytic subunit of phosphatase 2A.
Biological Activity
kemptide is a synthetic heptapeptide that acts as a substrate for camp-dependent protein kinase (pk) [1].cyclic amp-dependent protein kinase is the sole intracellular acceptor for cyclic amp in all cell types. protein phosphorylation by different types of protein kinase (pk) activities comprises a form of protein modification that plays an important role in the regulation of numerous biological processes [1][2].kemptide is a novel synthetic heptapeptide phosphate acceptor that acts as a substrate for camp-dependent protein kinase. kemptide had all the properties of a cytophilic substrate and could preserving cell membrane intactness when added to cultured cells. in the presence of extracellular atp and camp, different types of intact cells catalyzed the phosphorylation of kemptide with km values of 3-4 μm. kemptide phosphorylation was influenced by pki, the inhibitory protein specific for camp-pk [1]. kemptide was usually used as a substrate for detection of activities of soluble a-kinase isolated from guinea-pig lung parenchyma and from bovine tracheal smooth muscle [2][3].
