Quantitative cross-linking/mass spectrometry (QCLMS) is an emerging approach to study conformational changes of proteins and multi-subunit complexes. Distinguishing protein conformations requires reproducibly identifying and quantifying cross-linked peptides. Here we analyzed the variation between m...

We report the combination of protein-denaturation stability principles with quantitative cross-linking mass spectrometry using isobaric quantitative protein interaction reporter technologies. This method enables the evaluation of ligand-induced protein engagement through analysis of cross-link rela...

Dynamic proteins and multi-protein complexes govern most biological processes. Cross-linking/mass spectrometry (CLMS) is increasingly successful in providing residue-resolution data on static proteinaceous structures. In order to investigate the technical feasibility of recording dynamic processes u...

Quantitative cross-linking/mass spectrometry (QCLMS) provides increasing structural detail on altered protein states in solution. Accurate quantitation is a value in itself but may also be central to elucidating small differences between protein states. Hence, QCLMS could benefit from data independe...

We have developed quantitative cross-linking/mass spectrometry (QCLMS) to interrogate conformational rearrangements of proteins in solution. Our workflow was tested using a structurally well-described reference system, the human complement protein C3 and its activated cleavage product C3b. We found ...

The analysis of proteins and protein complexes by cross-linking mass spectrometry (XL-MS) has expanded in the last dec-ade. However, mostly used approaches suffer important limitations in term of efficiency and sensitivity. We describe here a new workflow based on the advanced use of the trifunction...

In this project, we compare the abundancies of cross-links in wild type and mutant iNOSoxyFMN-CaM complexes at specific interdomain interacting site and map the identified sites onto top AlphaFold 2 models for better understanding of iNOS protein dynamics.

We applied quantitative cross-linking/mass spectrometry (QCLMS) to interrogate the structure of iC3 (or C3(H2O)), the activated hydrolytic product of the abundant human complement protein C3. The slow but spontaneous and ubiquitous formation of iC3 from C3 initiates antibody-independent activation o...
