Title
Putrescine N-Methyltransferase in Cultured Roots of Hyoscyamus albus
Naruhiro Hibi; Toshihiro Fujita; Mika Hatano; et al. PLANT PHYSIOLOGY 1992. doi:10.1104/pp.100.2.826
Other claims from this paper (11)
- Observation High PMT activity occurred in roots of several solanaceous plants.
- Observation PMT showed an ordered bi-bi kinetic pattern with the reported Km and Ki values.
- Observation PMT methylated amines having two amino groups separated by three or four methylene groups.
- Observation Monoamines competitively inhibited PMT; three named monoamines were most inhibitory.
- Intervention effect Feeding n-butylamine reduced tropinone, tropine and pseudotropine at 1 mm.
- Intervention effect Feeding n-butylamine at 6 mm reduced hyoscyamine content by 52%.
- Intervention effect The 6beta-hydroxyhyoscyamine and scopolamine contents did not change.
- Intervention effect n-Butylamine greatly increased putrescine content, especially the conjugated pool.
- Intervention effect n-Butylamine slightly increased spermine content.
- Intervention effect n-Butylamine slightly decreased spermidine content.
- Mechanism The putrescine pool increase could account for the total alkaloid pool decrease.
