Aminoacylation activity of L. casei ValRS. (A) Purified L. casei ValRS was analyzed by 12% SDS-PAGE, and the gel was stained with Coomassie brilliant blue. The mass of L. casei ValRS is 96 kDa. (B) Aminoacylation activity of L. casei ValRS was measured for transcripts of tRNAVal (blue circles) and tRNAUnd (red circles). Error bars are SEM for three independent experiments.
