Towards understanding the tandem mass spectra of protonated oligopeptides. 1: mechanism of amide bond cleavage.
Paizs B, Suhai S. Paizs B, et al. Among authors: suhai s. J Am Soc Mass Spectrom. 2004 Jan;15(1):103-13. doi: 10.1016/j.jasms.2003.09.010. J Am Soc Mass Spectrom. 2004. PMID: 14698560
The mechanism of the cleavage of protonated amide bonds of oligopeptides is discussed in detail exploring the major energetic, kinetic, and entropy factors that determine the accessibility of the b(x)-y(z) (Paizs, B.; Suhai, S. Rapid Commun. Mass Spectrom. 2002, 16, …

Infrared spectroscopy and theoretical studies on gas-phase protonated leu-enkephalin and its fragments: direct experimental evidence for the mobile proton.
Polfer NC, Oomens J, Suhai S, Paizs B. Polfer NC, et al. Among authors: suhai s. J Am Chem Soc. 2007 May 9;129(18):5887-97. doi: 10.1021/ja068014d. Epub 2007 Apr 12. J Am Chem Soc. 2007. PMID: 17428052
For the former structure, two sites of proton attachment are observed, on the N-terminus and on the oxazolone ring nitrogen, as shown in a previous communication (Polfer, N. C.; Oomens, J.; Suhai, S.; Paizs, B. J. Am. Chem. Soc. 2005, 127, 17154-17155). Upon leaving …

Experimental and theoretical investigation of the main fragmentation pathways of protonated H-Gly-Gly-Sar-OH and H-Gly-Sar-Sar-OH.
Paizs B, Suhai S, Harrison AG. Paizs B, et al. Among authors: suhai s. J Am Soc Mass Spectrom. 2003 Dec;14(12):1454-69. doi: 10.1016/j.jasms.2003.07.001. J Am Soc Mass Spectrom. 2003. PMID: 14652192 Free article.
The main goal of these studies is to further investigate which factors determine the branching ratio of the b2-y1 (Paizs, B.; Suhai, S. Rapid Commun. Mass Spectrom. 2002, 16, 375.) and "diketopiperazine" (Cordero, M. ...
