Cytochrome P450 CYP1B1 (190-198) [Homo sapiens] is a peptide from Cytochrome c, which is a small heme protein found loosely associated with the inner membrane of the mitochondrion. Cytochromes c from certain eukaryotes, including plants and fungi but not higher animals, contains methylated lysine residues at specific positions1. Cytochrome c is a required cofactor for Apaf-1 function2.
