Hydroxocobalamin 127-143 methylmalonyl-CoA mutase Homo sapiens 93-96 7909321-1 1994 The mut0 mutation resulting in methylmalonyl CoA mutase (MCM) apoenzyme deficiency and methylmalonic aciduria is characterized by undetectable enzyme activity in cell extracts and low incorporation of propionate into cultured cells which is not stimulated by hydroxycobalamin. Hydroxocobalamin 259-275 methylmalonyl-CoA mutase Homo sapiens 57-60 36882-1 1979 We have examined the effect of addition of hydroxocobalamin to growth medium on the activity of the adenosylcobalamin-requiring enzyme methylmalonyl CoA mutase in normal human fibroblasts and in mutant human fibroblasts derived from patients with inherited methylmalonicacidemia. Hydroxocobalamin 43-59 methylmalonyl-CoA mutase Homo sapiens 135-159
