Captopril methylation by His-GST-METTL7B at various AdoMet concentrations in the presence or absence of AdoHcy: (A) His-GST-METTL7B catalyzed AdoMet-dependent methylation of captopril exhibits saturable Michaelis–Menten kinetics. Peak area ratio of methyl captopril to internal standard (PAR) versus concentration of AdoMet. (B) Inhibition of His-GST-METTL7B captopril methylation by AdoHcy. PAR versus AdoMet concentration curve at varying concentrations of AdoHcy. Data presented as mean ± s.d. n = 3 for (A) and average ± error (n = 2) for (B).
