Protein

Mitochondrial intermediate peptidase

Gene

OCT1

Organism
Saccharomyces cerevisiae (strain YJM789) (Baker's yeast)
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. Cleaves precursor proteins of respiratory components, including subunits of the electron transport chain and tricarboxylic acid cycle enzymes, and components of the mitochondrial genetic machinery, including ribosomal proteins, translation factors, and proteins required for mitochondrial DNA metabolism.

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

Enzyme regulationi

Stimulated by Fe2+.By similarity
