Aminotransferase reactions catalyzed by (a, b) alanine aminotransferase and (c, d) aspartate aminotransferase observed in human RBC lysates. Samples were incubated with 5 mM of each substrate and analyzed by 1H–13C NMR. The title of each plot indicates which substrates were added. Error bars represent S.E.M. (n = 3)
