**Background of AASDHPPT Recombinant Protein**
AASDHPPT (aminoadipate-semialdehyde dehydrogenase-phosphopantetheinyl transferase) is a bifunctional enzyme encoded by the *AASDHPPT* gene, primarily involved in the lysine degradation pathway and coenzyme A (CoA) biosynthesis. This mitochondrial enzyme catalyzes two critical steps: (1) the dehydrogenation of α-aminoadipate semialdehyde to α-aminoadipate via its aminoadipate-semialdehyde dehydrogenase domain, and (2) the phosphopantetheinylation of mitochondrial acyl carrier protein (ACP) through its phosphopantetheinyl transferase (PPT) domain, essential for activating ACP in fatty acid synthesis.
Recombinant AASDHPPT protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its structural and functional properties. Its dual enzymatic roles link lysine metabolism and CoA-dependent processes, impacting cellular energy homeostasis, lipid metabolism, and mitochondrial function. Dysregulation of AASDHPPT has been implicated in rare metabolic disorders and neurodegenerative conditions, underscoring its biomedical relevance.
Research on recombinant AASDHPPT aids in elucidating molecular mechanisms underlying metabolic diseases, drug targeting, and enzyme kinetics. It also serves as a tool for exploring therapeutic interventions, such as correcting CoA deficiencies or modulating lysine catabolism. Structural studies of the recombinant protein further reveal insights into domain interactions and catalytic mechanisms, facilitating the design of small-molecule modulators. Overall, AASDHPPT recombinant protein is a vital resource for advancing understanding of mitochondrial biochemistry and metabolic disease pathogenesis.
