Padua Research Archive, l’archivio istituzionale della produzione scientifica dell’Università degli Studi di Padova, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ateneo. Padua Research Archive utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishThe interaction between the HIV-1 Tat protein and the TAR RNA element in the nascent viral genomic transcript is required for viral replication. An 11-residue beta-peptide (1), an all-beta homologue of the Arg-rich region Tat 47-57, binds TAR RNA with K(d) = 29 +/- 4 nM. A control beta-peptide (2) in which all Arg side chains are replaced by Lys side chains shows increased affinity but decreased specificity for wild-type vs bulge-deleted TAR RNA, as do the alpha-peptide analogues of 1 and 2.
