Biochemical characterization of the methylmercaptopropionate:cob(I)alamin methyltransferase from Methanosarcina acetivorans
H. Fu, M. N. Goettge, W. W. Metcalf
This paper characterizes the MtpA methyltransferase from Methanosarcina acetivorans, showing it catalyzes methyl transfer from methylcob(III)alamin to mercaptopropionate but not to CoM, suggesting a second methyltransferase is needed for the full reaction.
