Analysis and parametric optimization of 1H off-resonance relaxation NMR experiments designed to map polypeptide self-recognition and other noncovalent interactions.
Milojevic J, Esposito V, Das R, Melacini G. Milojevic J, et al. Among authors: melacini g. J Phys Chem B. 2006 Oct 19;110(41):20664-70. doi: 10.1021/jp063194z. J Phys Chem B. 2006. PMID: 17034257
The measurement of 1H off-resonance nonselective relaxation rates (R(theta,ns)) has been recently proposed as an effective method to probe peptide self-recognition, opening new perspectives in the understanding of the prefibrillization oligomerization processes in a …

Analysis and optimization of saturation transfer difference NMR experiments designed to map early self-association events in amyloidogenic peptides.
Huang H, Milojevic J, Melacini G. Huang H, et al. Among authors: melacini g. J Phys Chem B. 2008 May 8;112(18):5795-802. doi: 10.1021/jp7118718. Epub 2008 Apr 15. J Phys Chem B. 2008. PMID: 18410162
Saturation transfer difference (STD) methods recently have been proposed to be a promising tool for self-recognition mapping at residue and atomic resolution in amyloidogenic peptides. Despite the significant potential of the STD approach for systems undergoing olig …

Hydration dynamics of the collagen triple helix by NMR.
Melacini G, Bonvin AM, Goodman M, Boelens R, Kaptein R. Melacini G, et al. J Mol Biol. 2000 Jul 28;300(5):1041-9. doi: 10.1006/jmbi.2000.3919. J Mol Biol. 2000. PMID: 10903852
In addition, the nanosecond to sub-nanosecond upper limits for water molecule residence times imply that hydration-dehydration events are not likely to be the rate-limiting step for triple helix self-recognition, complementing previous investigations on water dynami …

Mapping polypeptide self-recognition through (1)H off-resonance relaxation.
Esposito V, Das R, Melacini G. Esposito V, et al. Among authors: melacini g. J Am Chem Soc. 2005 Jul 6;127(26):9358-9. doi: 10.1021/ja051714i. J Am Chem Soc. 2005. PMID: 15984849
When applied to the Halpha spins of the Abeta (12-28) peptide, the proposed experiment provides a residue-resolution self-recognition map which is fully consistent with previous independent mutational studies. ...

Atomic-resolution map of the interactions between an amyloid inhibitor protein and amyloid β (Aβ) peptides in the monomer and protofibril states.
Algamal M, Ahmed R, Jafari N, Ahsan B, Ortega J, Melacini G. Algamal M, et al. Among authors: melacini g. J Biol Chem. 2017 Oct 20;292(42):17158-17168. doi: 10.1074/jbc.M117.792853. Epub 2017 Aug 10. J Biol Chem. 2017. PMID: 28798235 Free PMC article.
In both Abeta protofibrils and monomers, HSA targets key Abeta self-recognition sites spanning the beta strands found in cross-beta protofibril structures, leading to a net switch from direct to tethered contacts between the monomeric Abeta and the protofibril surfa …
