Abstract

The mitochondria from livers of normal and vitamin B12-deprived animals were compared. The rate of oxygen uptake (states 3 and 4) of mitochondria from vitamin B12-deprived livers was higher than that of normal mitochondria while the respiratory control index of B12-deprived mitochondria was lower than normal. Most Krebs cycle enzyme activities were increased in the hepatic mitochondria from B12-deprived animals. Two-dimensional gel electrophoresis of mitochondrial matrix proteins also indicated that an increase in Krebs cycle enzyme quantities occurred but the increase was not general for all mitochondrial proteins.
