title: Calmodulin binding proteins in rat liver mitochondria.
abstract: Calmodulin binding proteins have been found in submitochondrial fractions obtained from highly purified rat liver mitochondria. The matrix fraction contains two major calmodulin binding proteins: one, having Mr of 145,000, apparently is carbamoyl-phosphate synthetase. Another has a Mr of 58,000 and has not been associated with enzyme activities. A major calmodulin binding protein of unknown function and having Mr of 32,000 has been found in the Triton X-100 solubilizate of the inner membrane. Minor amounts of two calmodulin binding proteins having Mr of about 37,000 and 56,000 have been found in the outer membrane.
