Mitochondrial-processing peptidase subunit beta is an enzyme that in humans is encoded by the PMPCB gene.^[5]^[6] This gene is a member of the peptidase M16 family and encodes a protein with a zinc-binding motif. This protein is located in the mitochondrial matrix and catalyzes the cleavage of the leader peptides of precursor proteins newly imported into the mitochondria, though it only functions as part of a heterodimeric complex.^[6]
