Description générale

Sirtuin 3 (SIRT3) is a member of a family of NAD+-dependent protein deacetylases called sirtuins (SIRTs). In mammals, there are seven types of SIRTs (SIRT1 to 7). SIRT 3 is present in mitochondrial matrix.

Application

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.

Actions biochimiques/physiologiques

Sirtuin 3 (SIRT3) is thought to be involved in metabolism as its expression is suppressed in muscles of diabetic animals and increased in white and brown adipose tissues during calorie restriction (CR). This protein modulates the degree of acetylation and activity of acetyl-coenzyme A synthetase 2, an enzyme thought to be involved in energy production during starvation conditions in mammals. Up-regulation of this gene influences the expression of genes involved in mitochondrial function. During fasting, SIRT3 controls mitochondrial intermediary metabolism and fatty-acid use by deacetylating long-chain acyl coenzyme A dehydrogenase (LCAD). It is an essential modulator of basal ATP, and therefore, overall energy homeostasis.

Définition de l'unité

One unit is defined as the amount of enzyme required to deacetylate 1 pmol of substrate/min at 37°C.

Forme physique

Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20 and 20% glycerol.

Notes préparatoires

Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.
