protein insertion into mitochondrial inner membrane protein import into mitochondrial intermembrane space obsolete protein import into mitochondrial intermembrane space, conservative true protein import into mitochondrial intermembrane space, conservative protein transport into mitochondrial IMS, conservative OBSOLETE. The conservative import of proteins into the mitochondrial intermembrane space. The entire protein enters the matrix, and then the second targeting sequence directs the protein, presumably bound to a matrix protein, across the inner membrane to the intermembrane space. protein transport into mitochondrial intermembrane space, conservative GO:0045042 conservative protein transport into mitochondrial IMS protein import into mitochondrial IMS, conservative conservative mitochondrial intermembrane space protein import biological_process conservative protein transport into mitochondrial intermembrane space conservative mitochondrial IMS protein import This term was made obsolete because there is no 'conservative' process of protein import into the mitochondrial intermembrane space that is distinct from the more general parent; furthermore, 'conservative' is used in the literature to describe a pathway of import into the inner membrane rather than into the intermembrane space.
