SIRT5 also known as Sirtuin 5 is a mitochondrial protein with enzymatic activity as a lysine desuccinylase demalonylase and deglutarylase. It has a molecular mass of approximately 34 kDa. This protein is expressed highly in tissues with high metabolic activity like the liver heart and brain where it participates in regulating energy metabolism. The activity of SIRT5 affects cellular processes by removing post-translational modifications from lysine residues modulating proteins' functions and interactions in these tissues.
Biological function summary
SIRT5 functions as an important regulator of mitochondrial metabolism and influences cellular energy homeostasis. It is not part of larger complexes but it interacts with various metabolic enzymes to control their function. Through its deacylase activity SIRT5 affects the urea cycle and fatty acid oxidation by modifying key enzymes involved in these processes. Its role in maintaining a balance in energy production and consumption highlights its importance in cellular metabolism.
Pathways
SIRT5 is involved in both the tricarboxylic acid (TCA) cycle and the regulation of reactive oxygen species (ROS). Within the TCA cycle SIRT5 desuccinylates and activates enzymes like citrate synthase enhancing the cycle's efficiency. In regulating ROS SIRT5 reduces oxidative stress by affecting enzymes such as superoxide dismutase 2 (SOD2). Its interaction with these pathways and proteins reflects its role in maintaining metabolic health and cellular integrity.
Alterations in SIRT5 levels have been connected to metabolic diseases such as obesity and neurodegenerative disorders like Alzheimer's disease. In obesity SIRT5 dysregulation can lead to inefficient metabolic processes and energy imbalance. In Alzheimer’s decreased SIRT5 activity may contribute to increased mitochondrial oxidative stress implicated in disease progression. These connections highlight SIRT5’s significance in both metabolic and neurodegenerative contexts linking with proteins like AMPK in obesity and tau proteins in Alzheimer's disease.
