Biotinylated proteins in HEK293 whole cell extracts. (A) Proteins extracts were purified using monomeric avidin, resolved by SDS-PAGE,and and visualized using coomassie blue. Lanes 1 and 2 = independently prepared samples; lane 3 = markers. (B) Proteins containing both lysine biotinylation and methionine sulfoxidation marks were clustered by biological function.
