Import of cytochrome b2 to the mitochondrial intermembrane space: the tightly folded heme-binding domain makes import dependent upon matrix ATP.
Cytochrome b2 is synthesized as a precursor in the cytoplasm and imported to the intermembrane space of yeast mitochondria. We show here that the precursor contains a tightly folded heme-binding domain and that translocation of this domain across the outer membrane requires ATP. Surprisingly, it is...
