**Background of GMPS Recombinant Protein**
GMP synthase (GMPS) is a crucial enzyme in the purine biosynthesis pathway, catalyzing the conversion of xanthosine monophosphate (XMP) to guanosine monophosphate (GMP), an essential precursor for DNA and RNA synthesis. As a member of the glutamine amidotransferase family, GMPS utilizes ATP and glutamine to amidate XMP, ensuring the availability of guanine nucleotides for cellular processes like proliferation, signaling, and energy metabolism. Dysregulation of GMPS has been linked to diseases such as cancer and immune disorders, highlighting its role in maintaining nucleotide homeostasis.
Recombinant GMPS protein is produced via genetic engineering, typically using expression systems like *E. coli* or mammalian cells, to enable large-scale, high-purity production. This engineered protein retains the enzymatic activity of native GMPS, making it valuable for biochemical studies, drug discovery, and structural analysis. Researchers employ recombinant GMPS to investigate its catalytic mechanisms, screen for inhibitors, and explore its potential as a therapeutic target, particularly in cancers reliant on upregulated purine synthesis.
Additionally, GMPS recombinant protein aids in diagnosing metabolic disorders linked to purine deficiencies and serves as a tool in enzymology to study nucleotide metabolism pathways. Its production often involves affinity chromatography and activity assays to ensure functionality. By providing a controlled, abundant source of GMPS, recombinant technology advances both basic research and translational applications, bridging insights into cellular biology and clinical innovation.
