Predicted to enable several functions, including cobalamin binding activity; methylmalonyl-CoA mutase activity; and protein homodimerization activity. Predicted to be involved in homocysteine metabolic process and positive regulation of GTPase activity. Predicted to act upstream of or within post-embryonic development. Predicted to be located in mitochondrial matrix. Predicted to be active in mitochondrion. Human ortholog(s) of this gene implicated in methylmalonic aciduria due to methylmalonyl-CoA mutase deficiency. Orthologous to human MMUT (methylmalonyl-CoA mutase).
