The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.

The chemical reactions and pathways resulting in the breakdown of misfolded or attenuated proteins.

The import of proteins across the outer and inner mitochondrial membranes into the matrix. Unfolded proteins enter the mitochondrial matrix with a chaperone protein; the information required to target the precursor protein from the cytosol to the mitochondrial matrix is contained within its N-terminal matrix-targeting sequence. Translocation of precursors to the matrix occurs at the rare sites where the outer and inner membranes are close together.

The import of proteins into the space between the inner and outer mitochondrial membranes.

The import of proteins into the space between the inner and outer mitochondrial membranes.

Any process leading to the attainment of the full functional capacity of a protein.

Any process involved in maintaining the identity, size and shape of a meristem.

The chemical reactions and pathways resulting in the breakdown of a mitochondrial protein. This process is necessary to maintain the healthy state of mitochondria and is thought to occur via the induction of an intramitochondrial lysosome-like organelle that acts to eliminate the damaged oxidised mitochondrial proteins without destroying the mitochondrial structure.

A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.

The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae.

Protease complex of the mitochondrial inner membrane whose catalytic residues lie on the intermembrane space side of the inner membrane; involved in mitochondrial protein turnover. Contains a subunit belonging to the AAA family of ATP-dependent metalloproteases.

Any member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA. Plant plastids develop from a common type, the proplastid.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

Protease complex of the mitochondrial inner membrane whose catalytic residues lie on the intermembrane space side of the inner membrane; involved in mitochondrial protein turnover. Contains a subunit belonging to the AAA family of ATP-dependent metalloproteases.
