Phosphotyrosine mimic

WebIf you compare the chemical structures, glutamate (E) looks should be a better mimic for phosphoserine or phosphothreonine than aspartate (D). But sometimes D works better … WebAlternatively, phosphothioates can be formed by the treatment of dehydroalanine with sodium thiophosphate. (B) The Staudinger-phosphite reaction enabled selective reaction at azido-phenylalanine to introduce a phosphotyrosine mimic. (C) A stable phosphohistidine mimic was formed by reacting an alkyne-phosphonate with azidolysine.

Phosphotyrosine - an overview ScienceDirect Topics

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… WebJan 1, 1997 · Potent inhibition of protein-tyrosine phosphatase by phosphotyrosine-mimic containing cyclic peptides - ScienceDirect Bioorganic & Medicinal Chemistry Volume 5, … fischer click system https://andygilmorephotos.com
