[Molecular mechanism of calcium ion transport in mitochondria. II. Parameters of Ca2+ binding with glycoprotein and glycoprotein-peptide complex].
Calcium binding sites with high and low affinity are revealed while only sites with high affinity to the calcium ion (Kd = 5.8 x 10(-6) M) are found in the glycoprotein component of the complex. A model of the glycoprotein-peptide complex functioning in the system of electrogenic transport of Ca2+ in mitochondria is suggested.
