CC   -!- FUNCTION: Cleaves proteins, imported into the mitochondrion, to their
CC       mature size. While most mitochondrial precursor proteins are processed
CC       to the mature form in one step by mitochondrial processing peptidase
CC       (MPP), the sequential cleavage by MIP of an octapeptide after initial
CC       processing by MPP is a required step for a subgroup of nuclear-encoded
CC       precursor proteins destined for the matrix or the inner membrane (By
CC       similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Release of an N-terminal octapeptide as second stage of
CC         processing of some proteins imported into the mitochondrion.;
CC         EC=3.4.24.59;
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Note=Binds 1 zinc ion. {ECO:0000250};
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase M3 family. {ECO:0000305}.
