背景信息

**Background of PPA1 Recombinant Protein**

Purple acid phosphatase 1 (PPA1), also known as acid phosphatase 1 or uteroferrin-associated phosphatase, is a metalloenzyme belonging to the histidine acid phosphatase family. It is characterized by its conserved active-site motifs and a binuclear metal center, typically containing iron and zinc or manganese ions. PPA1 plays a critical role in cellular metabolism, including phosphate ester hydrolysis, reactive oxygen species (ROS) regulation, and bone resorption. Its expression is observed in diverse tissues, including bone, spleen, and macrophages, and it has been implicated in physiological processes such as immune response, osteoclast differentiation, and iron homeostasis.

The recombinant form of PPA1 is produced using biotechnological platforms, such as *E. coli* or mammalian expression systems, to enable large-scale, high-purity protein production. Recombinant PPA1 retains the enzymatic activity and structural integrity of its native counterpart, making it valuable for biochemical studies, drug discovery, and therapeutic applications. For instance, its role in bone metabolism has spurred research into osteoporosis treatments, while its antioxidant properties are explored for mitigating oxidative stress-related diseases.

PPA1's unique redox-active metal center also positions it as a model for studying metalloenzyme mechanisms. Dysregulation of PPA1 has been linked to pathological conditions, including cancer metastasis and neurodegenerative disorders, highlighting its potential as a biomarker or therapeutic target. Advances in recombinant DNA technology have facilitated structural and functional analyses, deepening insights into PPA1's biological significance and expanding its applications in both basic and applied biomedical research.
