MPP hydrolyzes presequence of inner membrane precursors

The alpha subunit (MAS2, Alpha-MPP) of the mitochondrial processing peptidase (MPP) binds presequences of mitochondrial precursors and the beta subunit (MAS1, Beta-MPP) cleaves the presequence (Yang et al. 1991, Geli 1993, Luciano et al. 1997, Luciano et al. 1998, Taylor et al. 2001, Dvorakova-Hola et al. 2010). After cleavage, proteins destined for the inner membrane are released laterally from TIM23 SORT into the membrane.
