To study the enzymes responsible for the establishment, recognition, and removal of this PTM, stable analogues are invaluable tools. We describe the design and synthesis of a 4-thioribosyl APRr peptide that has been assembled by solid phase synthesis. The key 4-thioribosyl serine building block was obtained in a stereoselective glycosylation reaction using an alkynylbenzoate 4-thioribosyl donor.Organic letters4-Thioribose Analogues of Adenosine Diphosphate Ribose (ADPr) Peptides.PMC10353035BB/W016613/1813369210634223107Codee JDCAhel IKistemaker HAVFilippov DVRack JGMVoorneveld JMadern JMvan der Marel GAfalse4-Thioribose Analogues of Adenosine Diphosphate Ribose (ADPr) Peptides.Adenosine diphosphate (ADP) ribosylation is an important post-translational modification (PTM) that plays a role in a wide variety of cellular processes.
