Vitamin B12-deficient rats were used to study the effects of feeding vitamin B12 on hepatic methylmalonyl-CoA mutase activity, which was decreased by the deficiency. A significant and rapid increase in the specific activity of the enzyme was caused by feeding vitamin B12 suggesting that the rate of synthesis of the enzyme protein is accelerated by the feeding
