Protein
Mitochondrial intermediate peptidase
Gene
OCT1, UM02435
Organism
Ustilago maydis (strain 521 / FGSC 9021) (Corn smut fungus)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Cleaves proteins, imported into the mitochondrion, to their mature size. While most mitochondrial precursor proteins are processed to the mature form in one step by mitochondrial processing peptidase (MPP), the sequential cleavage by MIP of an octapeptide after initial processing by MPP is a required step for a subgroup of nuclear-encoded precursor proteins destined for the matrix or the inner membrane By similarity.

Catalytic activityi

Release of an N-terminal octapeptide as second stage of processing of some proteins imported into the mitochondrion.

Cofactori

Binds 1 zinc ion By similarity.
