Protein attributes

Sequence length	525 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Cleaves presequences (transit peptides) from mitochondrial protein precursors By similarity.
Catalytic activity	Release of N-terminal transit peptides from precursor proteins imported into the mitochondrion, typically with Arg in position P2.
Subunit structure	Heterodimer of alpha and beta subunits By similarity.
Subcellular location	Mitochondrion matrix By similarity.
Sequence similarities	Belongs to the peptidase M16 family.
Caution	Does not seem to have a protease activity as it lack the zinc-binding site.
