Scientists identify key protein from mitochondria in energy regulation

Scientists identify key protein from mitochondria in energy regulation: "The mice that lacked SIRT3 also had many of the key markers of fat oxidation disorders, low energy levels and low tolerance to cold. Further investigation showed that higher levels of SIRT3 expression and activity increase the activity of this key enzyme in fat oxidation. However, a number of other proteins are acetylated in the mitochondria, an observation which suggests that other proteins may be involved."
