摘要: Viral homologs of the anti-apoptotic Bcl-2 proteins are highly diverged from their mammalian counterparts, yet they perform overlapping functions by binding and inhibiting BH3 (Bcl-2 homology 3)-motif-containing proteins. We investigated properties herpesvirus KSBcl-2, BHRF1, M11, as relate to those human Mcl-1, Bfl-1, Bcl-w, Bcl-xL, Bcl-2. Analysis sequence structure grooves showed that, despite low identity, M11 has structural similarities Bcl-2, Bcl-w. BHRF1 KSBcl-2 more structurally similar Mcl-1 than other Binding BH3-like peptides that specificity a restricted profile; preferences distinct Because herpesviruses associated with malignancies, we screened computationally designed peptide libraries using bacterial surface display identify selective binders or BHRF1. The resulting bound in preference but only modest over Mcl-1. Rational mutagenesis increased against dissociation constant 2.9nM for >1000-fold proteins, well >70-fold In addition providing new insights into viral specificity, this study will inform future work analyzing interaction homologous domains designing specific protein partners.
