Unveiling the role of histidine and tyrosine residues on the conformation of the avian prion hexarepeat domain.
Pietropaolo A, Muccioli L, Zannoni C, La Mendola D, Maccarrone G, Pappalardo G, Rizzarelli E. Pietropaolo A, et al. J Phys Chem B. 2008 Apr 24;112(16):5182-8. doi: 10.1021/jp710702q. Epub 2008 Apr 3. J Phys Chem B. 2008. PMID: 18386869
The prion protein (PrPC) is a glycoprotein that in mammals, differently from avians, can lead to prion diseases, by misfolding into a beta-sheet-rich pathogenic isoform (PrPSc). ...Proteins 2008, 70, 667-677), a conformational dependence on the protonation st …

Prion proteins leading to neurodegeneration.
La Mendola D, Pietropaolo A, Pappalardo G, Zannoni C, Rizzarelli E. La Mendola D, et al. Among authors: pietropaolo a. Curr Alzheimer Res. 2008 Dec;5(6):579-90. doi: 10.2174/156720508786898415. Curr Alzheimer Res. 2008. PMID: 19075585 Review.
Conformational preferences of the full chicken prion protein in solution and its differences with respect to mammals.
Pietropaolo A, Muccioli L, Zannoni C, Rizzarelli E. Pietropaolo A, et al. Chemphyschem. 2009 Jul 13;10(9-10):1500-10. doi: 10.1002/cphc.200900078. Chemphyschem. 2009. PMID: 19492390
We focus on the persistence of its secondary structure motifs using a recently proposed protein chirality indicator [A. Pietropaolo et al., Proteins 2008, 70, 667-677]. From this, we find a high rigidity of helix 2 (ChPrP178-195) and of the hexarepeat …

A quantitative measure of chirality inside nucleic acid databank.
Pietropaolo A, Parrinello M. Pietropaolo A, et al. Chirality. 2011 Aug;23(7):534-42. doi: 10.1002/chir.20961. Epub 2011 May 26. Chirality. 2011. PMID: 21618614
We show the capability of a chirality index (Pietropaolo et al., Proteins 2008;70:667-677) to investigate nucleic acid structures because of its high sensitivity to helical conformations. ...We also analyze RNA structures, where specific loops and hairpin motifs are …

A chirality-based metrics for free-energy calculations in biomolecular systems.
Pietropaolo A, Branduardi D, Bonomi M, Parrinello M. Pietropaolo A, et al. J Comput Chem. 2011 Sep;32(12):2627-37. doi: 10.1002/jcc.21842. Epub 2011 Jun 8. J Comput Chem. 2011. PMID: 21656787
In this work, we exploit the chirality index introduced in (Pietropaolo et al., Proteins 2008, 70, 667) as an effective descriptor of the secondary structure of proteins to explore their complex free-energy landscape. ...While the projections of the configurations found on …
