PGAM2 (phosphoglycerate mutase 2) is a key enzyme in glycolysis, catalyzing the conversion of 3-phosphoglycerate to 2-phosphoglycerate, a critical step in energy production. As a muscle-specific isoform of the PGAM family, it is encoded by the *PGAM2* gene and highly expressed in skeletal muscle, where rapid ATP generation is essential. Its activity supports cellular metabolism under both aerobic and anaerobic conditions, making it vital for muscle function and endurance.
Recombinant PGAM2 proteins are engineered using genetic cloning techniques, often expressed in bacterial (e.g., *E. coli*) or mammalian cell systems to study its structure, enzymatic mechanisms, and regulatory roles. Purification typically involves affinity chromatography to ensure high specificity and activity. These recombinant variants enable researchers to investigate PGAM2’s interactions with substrates, inhibitors, or potential therapeutic molecules.
Mutations in *PGAM2* are linked to glycogen storage disease type 10 (GSD10), a rare metabolic disorder characterized by exercise intolerance, muscle cramps, and myoglobinuria due to impaired glycolysis. Recombinant PGAM2 serves as a tool to model disease-associated mutations, screen drug candidates, or explore enzyme replacement therapies. Additionally, its role in cancer metabolism has drawn interest, as glycolytic enzymes are often dysregulated in tumors.
Beyond disease research, recombinant PGAM2 aids in structural biology (e.g., X-ray crystallography) to resolve its active site and allosteric regulation. It also supports biomarker studies, as altered PGAM2 levels correlate with muscle damage or metabolic syndromes. Overall, recombinant PGAM2 is a versatile reagent for advancing both basic science and translational applications in metabolism and genetic disorders.
