Protein attributes

Sequence length	794 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred 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.
