PAO4

Gene

PAO4

Protein

Probable polyamine oxidase 4

Organism

Arabidopsis thaliana

Length

497 amino acids

Function

Flavoenzyme involved in polyamine back-conversion (PubMed:18703589, PubMed:20532512, PubMed:21081665, PubMed:26925084). Catalyzes the oxidation of the secondary amino group of polyamines, such as spermine and spermidine (PubMed:18703589, PubMed:20532512, PubMed:21081665, PubMed:26925084). Substrate preference is spermine > spermidine (PubMed:18703589, PubMed:21081665). No activity detected when putrescine or N(1)-acetylspermine are used as substrates (PubMed:18703589). Plays an important role in the regulation of polyamine intracellular concentration (Probable).

Similarity

Belongs to the flavin monoamine oxidase family.

Function

Flavoenzyme involved in polyamine back-conversion (PubMed:21796433). Catalyzes the oxidation of the secondary amino group of polyamines, such as spermine (PubMed:21796433). Substrate preference is spermine > thermospermine > norspermine (PubMed:21796433). No activity detected when putrescine, spermidine or N(1)-acetylspermidine are used as substrates (PubMed:21796433). Plays an important role in the regulation of polyamine intracellular concentration (Probable).
