DE   stachydrine N-demethylase.
AN   L-proline betaine N-demethylase.
CA   (1) H(+) + L-proline betaine + NADPH + O2 = formaldehyde + H2O +
CA   N-methyl-L-proline + NADP(+).
CA   (2) H(+) + L-proline betaine + NADH + O2 = formaldehyde + H2O + N-methyl-
CA   L-proline + NAD(+).
CC   -!- The enzyme, characterized from the bacterium Sinorhizobium meliloti
CC       1021, consists of three different types of subunits.
CC   -!- The catalytic unit contains a Rieske [2Fe-2S] iron-sulfur cluster,
CC       and catalyzes the monooxygenation of a methyl group.
CC   -!- The resulting N-methoxyl group is unstable and decomposes
CC       spontaneously to form formaldehyde.
CC   -!- The other subunits are involved in the transfer of electrons from
CC       NAD(P)H to the catalytic subunit.
