Enzyme reactions

• Enzyme class 2: Chains A, L: E.C.3.4.24.64 - mitochondrial processing peptidase.
• Reaction: Release of N-terminal transit peptides from precursor proteins imported into the mitochondrion, typically with Arg in position P2.
• Cofactor: Zn(2+)
• Enzyme class 3: Chains P, D, E, O: E.C.7.1.1.8 - quinol--cytochrome-c reductase.
• Reaction: a quinol + 2 Fe(III)-[cytochrome c](out) = a quinone + 2 Fe(II)- [cytochrome c](out) + 2 H(+)(out)

Note, where more than one E.C. class is given (as above), each may correspond to a different protein domain or, in the case of polyprotein precursors, to a different mature protein.
