As a leading service provider of post-translational modification (PTM) analysis services, we also offer protein
glutarylation analysis services. Lysine glutarylation is a newly discovered protein PTM with reversible, dynamic and
conserved characteristics. With advanced experimental techniques and experienced experts, Creative
Proteomics can help our customers find new glutarylated proteins and modification sites in prokaryotes
and eukaryotes.
Overview of protein glutarylation
Protein glutarylation is the process of adding a glutaryl group to a specific lysine residue, i.e., adding a 5-carbon
acyl group to the lysine and changing the charge of the lysine from +1 to - 1. This protein modification may lead to
changes in the structure of the protein, affecting its physiological function and disrupting any interaction between
the lysine side chain of the modified protein and the negatively charged molecules. As a newly discovered protein
PTM, lysine glutarylation was first identified in 2014. Lysine glutarylation can occur in human cells, mice,
Escherichia coli, and Saccharomyces cerevisiae, and is widely present in eukaryotic and
prokaryotic cells. An increasing number of proteins have been identified as glutarylated proteins by mass
spectrometry (MS), both histones and non-histones. Lysine glutarylation has been shown to primarily involve diverse
cellular functions, including mitochondrial function, oxidative damage, and oxidative injury, and is associated with
various diseases, such as asthenospermia and organic aciduria.

Proteomics analysis of glutarylation
- MS-based lysine glutarylation analysis
The recent development of high-resolution liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods has made
it possible the identification of massive glutarylated proteins. Our protein glutarylation analysis service is based
on a proteomics approach that combines sensitive immunoaffinity purification and high-resolution LC-MS/MS to enable
qualitative and quantitative analysis of large-scale glutarylated proteins. Our services include protein extraction
and digestion, glutarylated peptide enrichment using anti-Kglu antibodies, LC-MS/MS analysis, and bioinformatics
analysis, facilitating the identification of novel glutarylated proteins and modification sites.
- Protein glutarylation prediction
Using computational tools and known protein interaction data, our team of experts can accurately identify the
substrates of lysine glutarylation and their corresponding sites, helping our customers to quickly, cost-effectively
and better understand the molecular mechanisms of lysine glutarylation.
Service features
- One-stop service.
- Antibody selection and screening, to identify glutarylated proteins and sites in new species/tissues with the
highest specificity antibodies.
- Since lysine glutarylation is unstable and low in abundance in vivo, focus on sample preparation and
use of improved methods.
- Large-scale identification of the enriched lysine glutarylation peptides by powerful MS analysis.
- Fast, reliable, and cost-effective protein glutarylation prediction.
