Abstract

HIV-1 viral budding involves binding of the viral Gagp6 protein to the ubiquitin E2 variant domain of the human tumor susceptibility gene 101 protein (Tsg101). Recognition of p6 by Tsg101 is mediated in part by a proline-rich motif that contains the sequence 'Pro-Thr-Ala- Pro'('PTAP'). Using the p6-derived 9-mer sequence 'PEPTAPPEE', we had previously improved peptide binding affinity by employing N-alkylglycine ('peptoid') residues. The ...
