MS Annika: A new Cross-Linking Search Engine


ABSTRACT: A cross linking mass spectrometry search engine was developed and implemented into Thermo Proteome Discoverer. The search engine is capable to handle several linker types as well as data input formats. To demonstrate its ability processing Bruker -ion mobility data, synthetic peptides (Beveridge, et. al., Nat. Commun., 2020, doi: 10.1038/s41467-020-14608-2) were analyzed and the respective files are availible here.

Cross-linking mass spectrometry (XL-MS) has become a powerful technique that enables insights into protein structures and protein interactions. The development of cleavable cross-linkers has further promoted XL-MS through search space reduction, thereby allowing for proteome-wide studies. These new analysis possibilities foster the development of new cross-linkers, which not every search engine can deal with out of the box. In addition, some search engines for XL-MS data also struggle with the v  ...[more]
