Other Information

**Key Characteristics** ME2 is a mitochondrial enzyme that exhibits NAD+-dependent malic enzyme activity, allowing it to catalyze the interconversion of malate and pyruvate. This reaction is crucial for maintaining energy balance and regulating the citric acid cycle. ME2 is also involved in the breakdown of malic acid, which is a key energy source for neurons. The enzyme's activity is tightly regulated by NADP, and its dysregulation has been implicated in various diseases, including neurodegenerative disorders. **Pathways and Functions** ME2 is involved in several key metabolic pathways, including: 1. **Citric Acid Cycle (TCA Cycle)**: ME2 participates in the TCA cycle by converting malate to pyruvate, which is then fed into the citric acid cycle to produce ATP, NADH, and FADH2. 2. **Electron Transfer Activity**: ME2 is involved in electron transfer reactions, facilitating the transfer of electrons from NADP to malic acid, which is then reduced to form NADPH. 3. **Malate Metabolic Process**: ME2 catalyzes the breakdown of malic acid, producing pyruvate, which can be used to generate ATP. 4. **Metabolism of Pyruvate**: ME2 is involved in the metabolism of pyruvate, which is a key energy source for neurons. 5. **Metal Ion Binding**: ME2 binds to metal ions, such as zinc and manganese, which are essential for its catalytic activity. **Clinical Significance** Dysregulation of ME2 has been implicated in various diseases, including: 1. **Neurodegenerative Disorders**: ME2 dysregulation has been linked to neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease, and Huntington's disease. 2. **Metabolic Disorders**: ME2 dysregulation has been implicated in metabolic disorders, such as type 2 diabetes and obesity. 3. **Cancer**: ME2 overexpression has been observed in various types of cancer, suggesting its potential role in tumorigenesis. 4. **Neurodevelopmental Disorders**: ME2 dysregulation has been linked to neurodevelopmental disorders, such as autism spectrum disorder and schizophrenia. In conclusion, ME2 is a crucial enzyme involved in various metabolic pathways, including the citric acid cycle, electron transfer, and metabolism of malic acid. Its dysregulation has been implicated in various diseases, highlighting the importance of ME2 in maintaining energy homeostasis and neural function. Further research is needed to fully elucidate the role of ME2 in human disease and to develop therapeutic strategies to modulate its activity.
