C GOT2 deacetylation is dependent on SIRT3 catalytic activity. Flag‐tagged GOT2 was ectopically expressed in HEK293T cells together with HA‐tagged wild‐type SIRT3 and a catalytically inactive mutant, SIRT3 H248Y. GOT2 proteins were purified by Flag beads, following Western blot to detect GOT2 K159 acetylation.
