Function edit

The C-terminal region of the product of the MMACHC gene is similar to TonB, a bacterial protein involved in energy transduction for cobalamin uptake.[5] The MMACHC gene product catalyzes the decyanation of cyanocobalamin as well as the dealkylation of alkylcobalamins including methylcobalamin and adenosylcobalamin.[6] This function has also been attributed to cobalamin reductases.[7] The MMACHC gene product and cobalamin reductases enable the interconversion of cyano- and alkylcobalamins.[8][9]

Clinical significance edit

Mutations are associated with combined homocystinuria and methylmalonic acidemia.[5][10][11][12][13]
