Methylputrescine oxidase

WebA SAM-dependent N-methylation of putrescine gives the N-methylputrescine product, which then undergoes oxidative deamination by the action of diamine oxidase to yield the aminoaldehyde. Schiff base formation confirms the biosynthesis of the N -methyl-Δ-pyrrolinium cation. Web30 nov. 2024 · The N -methyl Δ 1 -pyrrolinium cation is a simple pyrrolidine alkaloid and precursor of pharmacologically important tropane alkaloids. Silencing of pyrrolidine ketide synthase ( AbPyKS) in the roots of Atropa belladonna (Deadly Nightshade) reduces tropane alkaloid abundance and causes high N -methyl Δ 1 -pyrrolinium cation accumulation.
