Mmab - methylmalonic aciduria (cobalamin deficiency) cblB type homolog (human)

Predicted to enable cob(I)yrinic acid a,c-diamide adenosyltransferase activity and cobalamin binding activity. Predicted to be involved in cobalamin metabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; cardiovascular system; lung; nervous system; and trophectoderm. Human ortholog(s) of this gene implicated in inherited metabolic disorder and methylmalonic acidemia cblB type. Orthologous to human MMAB (metabolism of cobalamin associated B).
