cDNA from Nicotiana tabacum encoding PMT is introduced into the genome of a scopolamine-producing Hyoscyamus niger mediated by the disarmed Agrobacterium tumefaciens strain C58C1, which also carries Agrobacterium rhizogenes Ri plasmid pRiA4, and expressed under the control of the CaMV 35S promoter. Hairy root lines transformed with pmt present 5fold higher PMT activity than the control, and the methylputrescine levels of the resulting engineered hairy roots increase up to 5fold compared to the control and wild-type roots, but no increase in tropane alkaloids measured. After methyl jasmonate treatment, a considerable increase of PMTase and endogenous H6Hase as well as an increase in scopolamine content is found either in the transgenic hairy roots or the control

T1 progeny of transgenic Atropa belladonna, in which putrescine N-methyltransferase (EC 2.1.1.53) from Nicotiana tabacum (NtPMT) and hyoscyamine 6beta-hydroxylase (EC 1.14.11.14) from Hyoscyamus niger (HnH6H) are overexpressed, are established to investigate tropane alkaloids biosynthesis and distribution in ripe fruits, leaves, stems, primary roots and secondary roots under field conditions. Both NtPMT and HnH6H are detected at the transcriptional level in transgenic plants, whereas they are not detected in wild-type plants. Metabolically engineering Atropa belladonna based on overexpressing NtPMT and HnH6H shows a chemotype of rich scopolamine that greatly improves the commercial and pharmaceutical properties of Atropa belladonna

EXPRESSION
ORGANISM
UNIPROT
LITERATURE
Ag+ increases expression of putrescine N-methyltransferase I (maximum after 48 h). The expression of PMT1 reaches the highest level at 24 h treatment in ethanol
-
dark conditions and the absence of auxin upregulate enzyme promoter activity, with light being dominant to the repressive effects of auxin. Under highly repressive conditions for alkaloid synthesis, including normal culture conditions in the light, both reactive oxygen species scavengers result in significant induction of enzyme promoter activity. Treatment of callus with catalase results in the upregulation of enzyme promoter activity
-
isoform PMT1 expression is upregulated by methyl jasmonate in all tissues, reaching the highest level after 24 h of the treatment; isoform PMT2 expression is upregulated by methyl jasmonate in all tissues, reaching the highest level after 24 h of the treatment
treatments with diphenyleneiodinium chloride, Rose Bengal diacetate, and 1,2-dihydroxybenzene-3,5-disulfonic acid do not induce or repress enzyme expression
-
under normal callus growth conditions in the presence of light and auxin, enzyme promoter activity is strongly repressed

analysis
-
convenient and accurate enzyme-coupled colorimetric PMT assay, based on the conversion of S-adenosyl-L-homocysteine by 5'-methylthioacenosine/S-adenosylhomocysteine nucleosidase and S-ribosylhomocysteine lyase
synthesis
additional information
synthesis
-
overexpression of enzyme leads to enhanced N-methylputrescine levels, but the subsequent alkaloid metabolites are not affected
synthesis
-
overexpression of enzyme is not sufficient to boost scopolamine biosynthesis. Simultaneous overexpression of enzyme and hyoscyamine 6 beta-hydroxylase results in sígnificant enhancement of scopolamine accumulation
additional information
-
protein model of PMT based on the crystal structure of SPDS suggests that overall protein folds are comparable, the respective cosubstrates S-adenosylmethionine and decarboxylated S-adenosylmethionine, however, appear to bind differentially to the active sites of both enzymes, and the substrate putrescine adopts a different position
additional information
-
different polyamine catabolic processes in hypergeous and hypogeous tissues, duality in polyamine catabolic pathways involves correlation of amine oxidases with PMT for the production of nicotine alkaloids, and with POX for the lignification, cell wall formation, and vascular differentiation
additional information
-
chimera proteins obtained by fusion of fragments of Solanum tuberosum pmt2 and Hyoscyamus niger pmt are active as PMT
additional information
-
no functional protein translated from Solanum tuberosum pmt2, chimera proteins obtained by fusion of fragments of Solanum tuberosum pmt2 and Hyoscyamus niger pmt are active as PMT, if the initial part of pmt2 is used, indicating that a mutation in the terminal part of the gene causes insolubility of the enzyme
additional information
-
the deduced amino acid sequence of Anisodus tanguticus shows 92% identity with both Hyoscyamus niger and Atropa belladonna PMT
