DE   [methionine synthase] reductase.
AN   [methionine synthase]-cobalamin methyltransferase (cob(II)alamin
AN   reducing).
AN   methionine synthase cob(II)alamin reductase (methylating).
AN   methionine synthase reductase.
CA   H(+) + 2 methylcob(III)alamin-[methionine synthase] + NADP(+) +
CA   2 S-adenosyl-L-homocysteine = 2 cob(II)alamin-[methionine synthase] +
CA   NADPH + 2 S-adenosyl-L-methionine.
CC   -!- The substrate of the enzyme is the inactivated cobalt(II) form of
CC       EC 2.1.1.13.
CC   -!- Electrons are transferred from NADPH to FAD to FMN.
CC   -!- Formerly EC 2.1.1.135.
