This study maps metaproteomic responses of human gut microbiota to 312 drugs, identifying 47 compounds that significantly alter microbial protein profiles and reveal functional state shifts.

This study introduces a streamlined TMT labeling method using pre-aliquoted dry reagents, improving efficiency and reducing variability in proteomic and metaproteomic analyses.

The paper characterizes lysine acetylation in the human gut microbiome and identifies differential acetylation patterns in Crohn’s disease patients.

pepFunk improves functional analysis of metaproteomic gut microbiome data by focusing on peptides rather than proteins, identifying more enriched KEGG pathways.

The paper introduces a chemoenzymatic method to quantitatively analyze N-glycan types on glycoproteins, demonstrating its application in characterizing glycan heterogeneity in IgG1 and MCF7 cells.
