7. The amino acid ornithine is converted to biologically important polyamines such as spermine. The first step of this biosynthesis involves the enzyme ornithine decarboxylase. Lysine 69 on ornithine decarboxylase (ODC) binds the cofactor pyridoxal phosphate (PLP) through an imine bond (see below). Ornithine displaces the lysine to create a new imine bond with PLP.
