H Mapping the major lysine residue(s) of acetylation in GOT2 whose acetylation can affect protein interaction between GOT2 and MDH2. Putative acetylated residues were divided into six groups according to their position in the structure of GOT2. Each group of putative acetylated lysine (K) sites was mutated to arginine (R), and the deacetylated mimic K‐to‐R mutants were examined for their protein association with ectopically expressed Myc‐MDH2 by Western blot analysis.
