Lysine acylations of humangut microbiome


ABSTRACT: In this study we developed an analytical workflow by integrating a serial immunoaffinity enrichment with high resolution mass spectrometry and unrestricted metaproteomic database search strategy, which enables efficient and comprehensive identification and quantification of lysine acetylation, propinoylation and succinylation in microbiomes.

Lysine acylations are important post-translational modifications that are present in both eukaryotes and prokaryotes and regulate diverse cellular functions. Our knowledge of the microbiome lysine acylation remains limited due to the lack of efficient analytical and bioinformatics methods for complex microbial communities. Here, we show that the serial enrichment using motif antibodies successfully captures peptides containing lysine acetylation, propionylation, and succinylation from human gut  ...[more]
