Abstract

Mass spectrometry-based proteomics is essential for understanding protein composition and function, yet traditional sequence database-based methods face challenges in identifying novel peptides, post-translational modifications, and diverse proteomes. De novo peptide sequencing, which operates independently of sequence databases, offers a powerful approach for uncovering these unknown peptides. However, the lack of consistent evaluation frameworks for the growing array of deep learning-based de novo sequencing tools limits their adoption and effective application. Here, we introduce a comprehensive, community-driven benchmarking resource designed to assess the performance of various de novo sequencing tools across a broad range of experimental conditions and proteomic applications. Our benchmark employs heterogeneous datasets to establish a standardizedevaluation framework, providing a transparent, evolving resource accessible through an interactive online dashboard. This benchmark is anticipated to offer key insights into tool performance, aiding researchers in selecting suitable tools and identifying areas for future refinement and development in de novo peptide sequencing.
