NCIt definition : Cyanocobalamin reductase / alkylcobalamin dealkylase (282 aa, 32 kDa) is encoded
by the human MMACHC gene. This protein is involved in cobalamin transport and the
decyanation of cyanocob(III)alamin (cyanocobalamin, CNCbl) to yield cob(II)alamin
and cyanide and the dealkylation of alkylcob(III)alamins using a thiolate of glutathione
to generate cob(I)alamin and the corresponding glutathione thioether.;
