Autoradiogram of TaVC activity. TaVC was individually combined with phosphopantetheinylated TaB, TaE, Ta1-T6, Ta1-T7 and Ta1-T8 in the presence of radiolabeled acyl-CoA thioesters and subjected to denaturing gel electrophoresis. The phosphopantetheinyl transferase Sfp remaining from in situ generation of the holo-thiolation domains is visible. (Left) Coomassie-stained gel; molecular weight standards are 15 kD, 21 kD, 28 kD, 41 kD, and 58 kD. (Right) Autoradiogram; molecular weight standards are 15 kD, 21 kD, 28 kD, and 45 kD. Ac, acetyl; Prop, propionyl; Mal, malonyl; Memal, methylmalonyl.
