**Background of Recombinant Human PDSS1 Protein**
The **recombinant human PDSS1 (Decaprenyl Diphosphate Synthase Subunit 1)** protein is a key enzyme involved in the biosynthesis of coenzyme Q (CoQ), a lipid-soluble molecule essential for mitochondrial electron transport and cellular energy production. PDSS1 functions as a subunit of the heterotetrameric enzyme complex (PDSS1-PDSS2) responsible for synthesizing polyprenyl diphosphate, a precursor for CoQ and other isoprenoid compounds. This protein localizes primarily to mitochondria and plays a critical role in sustaining oxidative phosphorylation and protecting cells from reactive oxygen species (ROS).
PDSS1 mutations are associated with CoQ10 deficiency disorders, manifesting as mitochondrial encephalomyopathy, renal dysfunction, or early-onset multisystemic conditions. Recombinant PDSS1 is produced using expression systems (e.g., *E. coli* or mammalian cells) to study its enzymatic activity, structure-function relationships, and pathological mechanisms. It serves as a vital tool for drug screening, gene therapy research, and understanding mitochondrial dysfunction in aging, neurodegenerative diseases, and metabolic syndromes. Its recombinant form enables standardized, scalable study of CoQ biosynthesis pathways and therapeutic interventions.
