Abstract |
The in vitro methylation of inorganic mercury has been demonstrated using an acetone precipitated protein fraction from Pisum sativum and S-adenosylmethionine as the methyl-donating compound. A time course of the enzymatic formation of methylmercury has shown that the maximum methylmercury concentration occurred after one hour of incubation of the substrates with the enzyme system. At all subsequent incubation times reduced concentrations of methylmercury in the reaction mixture were observed. When a time course for the in vivo methylation of inorganic mercury was done using an infiltration and incubation procedure, the maximum concentration of methylmercury was observed after 10 hours of incubation. All subsequent incubation periods produced lesser amounts of methylmercury. The results suggest that the methylmercury is an intermediate compound in the mercury pathway in peas (Pisum sativum). |
