This enzyme participates in 6 metabolic pathways: methionine metabolism, tyrosine metabolism, phenylalanine metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, novobiocin biosynthesis, and alkaloid biosynthesis i.
This methionine may be replaced by alanine or other residues, making it resistant to oxidation thereby keeping the protein active in the presence of bleach.
