2.1.1.13 | 5-methyltetrahydrofolate + L-homocysteine |
methionine biosynthesis |
2.1.1.13 | 5-methyltetrahydrofolate + L-homocysteine |
gene expression is induced by light, but more strongly induced under salt, drought and cold stresses and by treatment with ABA or H2O2 |
2.1.1.13 | 5-methyltetrahydrofolate + L-homocysteine |
homocysteine increases methionine synthase mRNA level |
2.1.1.13 | N5-methyltetrahydrofolate + L-homocysteine |
transcription is not regulated by Met, but is enhanced by homocysteine and repressed by choline and betaine. Synthesis of the enzyme is also regulated posttranscriptionally |
