Protein

Mitochondrial intermediate peptidase 1

Gene

OCT1

Organism
Cryptococcus neoformans var. neoformans serotype D (strain JEC21 / ATCC MYA-565) (Filobasidiella neoformans)
Status
Reviewed-Annotation score: -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
