Protein

Mitochondrial intermediate peptidase

Gene

OCT1

Organism
Schizophyllum commune (Split gill 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).By similarity

Catalytic activityi

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

Cofactori

Zn2+By similarityNote: Binds 1 zinc ion.By similarity
