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.
CC Cleaves precursor proteins of respiratory components, including
CC subunits of the electron transport chain and tricarboxylic acid cycle
CC enzymes, and components of the mitochondrial genetic machinery,
CC including ribosomal proteins, translation factors, and proteins
CC required for mitochondrial DNA metabolism. {ECO:0000269|PubMed:7593000,
CC ECO:0000269|PubMed:8035833}.
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 -!- ACTIVITY REGULATION: Stimulated by Fe(2+).
CC {ECO:0000269|PubMed:10332043}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000269|PubMed:14562095, ECO:0000269|PubMed:16823961,
CC ECO:0000269|PubMed:8831696}.
CC -!- DISRUPTION PHENOTYPE: Simultaneous disruption of the mitochondrial
CC presequence protease CYM1 results in synthetic lethality in respiratory
CC conditions. {ECO:0000269|PubMed:25176146}.
CC -!- MISCELLANEOUS: Present with 2690 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the peptidase M3 family. {ECO:0000305}.
