the HyCoSuL approach, we designed and synthesized novel and selective fluorogenic substrates for each of these three constitutive 20S proteasome activities and applied them to assess inhibition of proteasome subunits by MG-132 and a clinically used inhibitor bortezomib. Our results confirm the utility of designed substrates in biochemical assays. Furthermore, selective peptide sequences obtained in this
Over the past decades, peptidenucleicacid/DNA (PNA:DNA) duplex stability has been improved via backbone modification, often achieved via introducing an amino acid side chain at the α- or γ-position in the PNA sequence. It was previously shown that interstrand cross-linking can further enhance the binding event. In this work, we combined both strategies to fine-tune PNA crosslinking towards single
