Malonylation Analysis Service

Malonylation, as a newly discovered type of acylation modification in recent years, has an important role in metabolic processes, especially energy metabolism, inflammatory response and photosynthesis. Creative Proteomics offers high-quality malonylation analysis services, including identification, quantification and characterization of protein malonylation modifications, providing valuable insights into your protein research.

What is Malonylation

Malonylation is an evolutionarily conserved type of protein post-translational modification (PTM) occurring on lysine that was first identified in 2011. It occurs in dependence on the transfer of a negatively charged malonyl group from malonyl-CoA to the positively charged ε-amino group of lysine. Like many other acyl-CoA species, malonyl-CoA is an intermediate metabolite of the fatty acid synthesis pathway and is an endogenous provider of the malonyl group required for lysine malonylation. Modification of acyl-CoA can occur by enzymatic or nonenzymatic pathways, but acylation in mitochondria is generally considered to be nonenzymatic.

Malonylation alters the electrostatic interactions of lysine with other amino acids and its protein conformation, and may even affect its binding to target proteins. Malonylation has been shown to be present in a variety of metabolic pathways such as fatty acid synthesis and, mitochondrial respiration, glycolysis, plant stress tolerance, inflammatory response, photosynthesis, and others. Malonylation, as a widespread PTM, plays a crucial role in protein and biological process research, among others.

Applications of Malonylation Analysis

Malonylation usually occurs in mitochondria and plays an important role in many aspects of mitochondrial respiration, glycolysis, diabetes, as well as plant photosynthesis and stress tolerance studies. Protein malonylation is an important aspect of biological and pharmaceutical research that should not be ignored and has a wide range of applications.

• Sample Preparation
  Proper extraction and preparation of proteins from biological samples to ensure preservation of malonylated proteins.
• Malonylation Enrichment
  Enrichment techniques are employed to isolate malonylate proteins or peptides. This step is crucial as malonylation modifications are often present in low abundance compared to unmodified proteins.
• Detection
  WB, protein microarrays and LC-MS/MS are powerful tools for the identification and quantification of malonylate peptides, and they provide detection information that facilitates a comprehensive analysis of malonylation.
• Bioinformatics Analysis
  Advanced bioinformatics tools are used to analyze data, identify malonylate peptides, and map these modifications to protein sequences.
• Result Delivery
  After professional data analysis, we deliver results quickly and consistently.
