Identification of calmodulin-binding proteins in pure mitochondria by photoaffinity labeling.
Calmodulin-binding proteins (CaM-BPs) were identified in the submitochondrial fractions obtained from highly purified rat liver mitochondria. The matrix fraction contained five CaM-BPs with apparent molecular weights (MW) of 27K, 38K, 47K, 76K, and 84K Da in a Ca solution. Electron transfer particles also contained five CaM-BPs, but their MWs were 31K, 35K, 53K, 66K, and 73K in a Ca solution. Nonspecific calcium-independent CaM-BPs were also identified in matrix fractions, having MWs of 10K, 25K, and 49K Da.
