Other Information

**Key Characteristics** HPD is a dioxygenase enzyme that belongs to the family of non-heme iron-containing enzymes. It is a homodimeric protein, consisting of two identical subunits that are connected by a disulfide bridge. The enzyme has a molecular mass of approximately 62 kDa and is primarily localized in the cytosol and endoplasmic reticulum membrane. HPD is a metal ion-dependent enzyme that requires iron ions for its catalytic activity. The enzyme is also capable of binding metal ions, such as copper and zinc, which are essential for its function. **Pathways and Functions** HPD plays a central role in the catabolic pathways of phenylalanine and tyrosine, which are essential amino acids involved in various physiological processes. The HPD-mediated degradation of these amino acids is crucial for the maintenance of proper amino acid homeostasis and the prevention of amino acid toxicity. In addition to its role in amino acid catabolism, HPD is also involved in the regulation of various cellular processes, including: 1. **Metabolism of amino acids and derivatives**: HPD is involved in the degradation of phenylalanine and tyrosine, which are essential amino acids that play critical roles in various physiological processes. 2. **Metal ion binding**: HPD is capable of binding metal ions, such as copper and zinc, which are essential for its catalytic activity. 3. **Protein homodimerization activity**: HPD is a homodimeric protein that consists of two identical subunits connected by a disulfide bridge. 4. **Cytosol and endoplasmic reticulum membrane localization**: HPD is primarily localized in the cytosol and endoplasmic reticulum membrane, where it is involved in the regulation of various cellular processes. **Clinical Significance** Dysregulation of HPD activity has been implicated in various human diseases, including: 1. **Phenylketonuria (PKU)**: PKU is a genetic disorder caused by mutations in the HPD gene, leading to impaired phenylalanine degradation and accumulation of toxic metabolites. 2. **Tyrosinemia type II**: Tyrosinemia type II is a genetic disorder caused by mutations in the HPD gene, leading to impaired tyrosine degradation and accumulation of toxic metabolites. 3. **Cancer**: Aberrant expression of HPD has been implicated in various types of cancer, including colorectal, breast, and lung cancer. 4. **Neurological disorders**: HPD has been implicated in the regulation of various neurological disorders, including Parkinson's disease and Alzheimer's disease. In conclusion, the HPD gene is a crucial enzyme involved in the catabolic pathways of phenylalanine and tyrosine. Its dysregulation has been implicated in various human diseases, highlighting the importance of this enzyme in maintaining proper amino acid homeostasis and preventing amino acid toxicity.
