Isolation of a major hydrophobic protein of the mitochondrial inner membrane

A protein of molecular weight 29,000 has been isolated from the mitochondrial inner membrane. It is a major component of Racker's hydrophobic protein mixture and is also rather selectively released from the inner membrane by lysolecithin treatment. Data indicate that the 29,000 component may be as much as 10% of the total protein of the inner membrane.
