F, G Knockdown of SIRT3 diminishes the effect of glucose or glutamine on changing GOT2 K159 acetylation. Flag‐tagged GOT2 was ectopically expressed in HEK293T cells without or with transient SIRT3 knockdown. These cells were treated with different concentrations of glucose (F) and glutamine (G) as indicated. GOT2 proteins were purified by Flag beads, and the K159 acetylation level of GOT2 was determined by Western blot analysis.
