UniProt entry A0A314KPU1 for Nicotiana attenuata AMO_3

UniProt assigns exact N-methylputrescine oxidase chemistry to AMO_3

"CC -!- CATALYTIC ACTIVITY: Reaction=N-methylputrescine + O2 + H2O = 4-methylaminobutanal + H2O2 + NH4(+)"
UniProt places AMO_3 in nicotine biosynthesis and the peroxisome

"CC -!- PATHWAY: Alkaloid biosynthesis; nicotine biosynthesis."

NaMPO1 AMO_3 candidate notes

MPO is part of the minimal upstream module that feeds the completed nicotine pathway

"The glucosylation preprint keeps MPO in the minimal upstream nicotine module by using ODC, PMT, and MPO to generate N-methylpyrrolinium, and it places MPO1 among the genes most correlated with A622."
AMO_3 is the best current sequence-backed NICAT ortholog to tobacco MPO1

"The 2026-04-05 mapping dive assigns NaMPO1 to AMO_3 / A0A314KPU1 as the best current sequence-backed NICAT ortholog to tobacco NtMPO1."

Deep research report on NaMPO1/AMO_3 (Falcon/Edison Scientific Literature)

No primary publication directly characterizes A0A314KPU1 / AMO_3 in N. attenuata; annotation rests on amine oxidase family inference (copper-dependent flavin-free amine oxidases that oxidize N-methylputrescine to 4-methylaminobutanal) plus the nicotine-pathway genomic and co-expression context placing this candidate as the attenuata ortholog of tobacco NtMPO1 in the ODC-PMT-MPO upstream pyrrolinium-branch module that feeds the completed nicotine pathway.
