Unlike intermolecular disulfide bonds, other protein cross-links arising from oxidative modifications cannot be reversed and are presumably more toxic to cells because they may accumulate and induce protein aggregation. However, most of these irrever

The proteasome is the primary contributor in intracellular proteolysis. Oxidized or unstructured proteins can be degraded via a ubiquitin- and ATP-independent process by the free 20S proteasome (20SPT). The mechanism by which these proteins enter the

Fragmentation features of intermolecular cross-linked peptides using N-hydroxy- succinimide esters by MALDI- and ESI-MS/MS for use in structural proteomics

Autor: Amadeu H. Iglesias, Luiz Fernando Arruda Santos, Fabio C. Gozzo

Publikováno v: Journal of mass spectrometry : JMS. 46(8)

The use of mass spectrometry coupled with chemical cross-linking of proteins has become one of the most useful tools for proteins structure and interactions studies. One of the challenges in these studies is the identification of the cross-linked pep

IRMPD and ECD fragmentation of intermolecular cross-linked peptides

Autor: Marcos N. Eberlin, Luiz Fernando Arruda Santos, Fabio C. Gozzo

Publikováno v: Journal of mass spectrometry : JMS. 46(3)

Despite the increasing number of studies using mass spectrometry for three dimensional analyses of proteins (MS3D), the identification of cross-linked peptides remains a bottleneck of the method. One of the main reasons for this is the lack of knowle

Traveling-wave ion mobility mass spectrometry analysis of isomeric modified peptides arising from chemical cross-linking

Autor: Eduardo Jorge Pilau, Fabio C. Gozzo, Alexandre F. Gomes, Amadeu H. Iglesias, Luiz Fernando Arruda Santos

Publikováno v: Journal of the American Society for Mass Spectrometry. 21(12)

Traveling-wave ion mobility (TWIM) coupled to mass spectrometry (MS) has emerged as a powerful tool for structural and conformational analysis of proteins and peptides, allowing the analysis of isomeric peptides (or proteins) with the same sequence b
