TerSyn Pathway : Menthol Biosynthesis |
Reaction: EC 1.1.1.208 : (+)-neomenthol + NADP+ = (-)-menthone + NADPH + H+
Reaction: EC 1.1.1.207 : (-)-menthol + NADP+ = (-)-menthone + NADPH + H+
Reaction: EC 1.14.13.104 : (+)-pulegone + NADPH + H+ + O2 = (+)-menthofuran + NADP+ + H2O
Reaction: EC 1.3.1.81: (1) (-)-menthone + NADP+ = (+)-pulegone + NADPH + H+
(2) (+)-isomenthone + NADP+ = (+)-pulegone + NADPH + H+ Reaction: EC 1.3.1.82 : (+)-cis-isopulegone + NADP+ = (-)-isopiperitenone + NADPH + H+
Reaction: EC 1.1.1.223 : (-)-trans-isopiperitenol + NAD+ = (-)-isopiperitenone + NADH + H+
Reaction: EC 1.14.13.47: (S)-limonene + NADPH + H+ + O2 = (-)-trans-isopiperitenol + NADP+ + H2O
Reaction: EC 4.2.3.16 : geranyl diphosphate = (S)-limonene + diphosphate |
Menthol biosynthesis pathway mapping The Menthol Biosynthesis Pathway; Mapping Table below shows the complete pathway enzymes responsible for synthesis of Menthol in Mentha Species. The first row shows the enzymes (E1,E2,E3,E4,E5,E6,E7) sequentially as shown in the above figure for menthol biosynthesis; below it shows the step by step mapping of each enzyme with different plants and represent the orthology with Mentha. In the table [YES] represent the presence of the particular ortholog enzyme with its accession number and %Identity. Here [NO] represent the absence of enzyme in that plant i.e it does not show any orthology with particular enzyme. . ....more. |
