Webp-Carboxymethyl- l-phenylalanine (pCMF), a phosphotyrosine (pTyr) mimetic that is resistant to protein tyrosine phosphatase hydrolysis, was cotranslationally incorporated into proteins in Escherichia coli using an orthogonal amber … Phosphomimetics are amino acid substitutions that mimic a phosphorylated protein, thereby activating (or deactivating) the protein. Within cells, proteins are commonly modified at serine, tyrosine and threonine amino acids by adding a phosphate group. Phosphorylation is a common mode of activating or deactivating a protein as a form of regulation. However some non-phosphoryla…
WebJul 22, 2013 · The fluorogenic phosphotyrosine mimic pCAP provides a facile assay for PTP activity in several different applications, as highlighted in this review. In addition to providing a convenient kinetic assay for PTP activity, pCAP peptides are excellent substrates for high-throughput screens aimed at discovering new PTP inhibitors. WebJan 15, 2014 · Phosphotyrosine peptides are often used in these assays, but their use is complicated by either poor sensitivity or the need for indirect detection methods, among …
