||Recombinant human MMAB protein (33-250aa), fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.
||MMAB is a protein that catalyzes the final step in the conversion of vitamin B(12) into adenosylcobalamin (AdoCbl), a vitamin B12 containing coenzyme for methylmalonyl-CoA mutase(MCM). Impaired MMAB activity leads to the inherited disorder vitamin B12 dependent methylmalonic aciduria linked to the cblB complementation group.
