Sequence length785 AA.
Sequence statusComplete.
Sequence processingThe displayed sequence is further processed into a mature form.
Protein existenceInferred from homology

General annotation (Comments)

Function

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 activity

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

Cofactor

Binds 1 zinc ion By similarity.

Subcellular location

Mitochondrion matrix By similarity.

Sequence similarities

Belongs to the peptidase M3 family.
