Recombinant human dimethylglycine dehydrogenase (DMGDH) is a mitochondrial enzyme critical in choline metabolism. It catalyzes the oxidative demethylation of dimethylglycine (DMG) to sarcosine, producing hydrogen peroxide and 5.10-methylene-tetrahydrofolate. This reaction links choline catabolism to the folate cycle, influencing one-carbon metabolism essential for nucleotide synthesis and epigenetic regulation. DMGDH dysfunction is linked to rare inborn errors, causing elevated DMG and reduced sarcosine levels, with phenotypes ranging from cardiomyopathy to muscle weakness.
Recombinant DMGDH proteins are engineered using expression systems like E. coli or mammalian cells, often tagged for purification. They retain enzymatic activity, enabling structural studies, inhibitor screening, and disease modeling. Research focuses on understanding its redox cofactor (FAD) dependency, substrate specificity, and role in metabolic disorders. Recent studies also explore its potential as a biomarker for mitochondrial dysfunction or metabolic syndrome. The recombinant protein aids in elucidating molecular mechanisms of DMGDH deficiencies and developing therapeutic interventions targeting choline metabolism pathways.
