Abstract:
This study shows that the plant mitochondrial nucleoside diphosphate kinase (mNDPK) localizes to both the intermembrane space and to the mitochondrial inner membrane. We show that mNDPK is very firmly attached to the membrane. Co-immunoprecipitation experiments identified the adenine nucleotide translocator as an interaction partner. This is the first report showing a direct association between these two proteins, although previous studies have shown metabolic cooperation between them. Possible consequences for mitochondrial energy metabolism are discussed.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
Mitochondrial Protein Sorting
Most of these mitochondrial proteins are encoded by the nucleus and imported to the mitochondria as unfolded or loosely folded precursors. Mitochondrial precursors...
