    2.1.1.295 | malfunction |
an SLL0418 partial knockout mutant accumulates beta-tocopherol with no effect in the overall tocopherol content of the cell |
724991 |
| 2.1.1.295 | physiological function |
the enzyme is involved in the biosynthesis of plastoquinol, as well as vitamin E (tocopherols and tocotrienols) |
724991 |
| 2.1.1.295 | physiological function |
loss-of-function mutant seedlings are pale green and do not survive beyond 7 days in soil. Mutation does not affect embryo growth and development |
728471 |
| 2.1.1.295 | physiological function |
loss of enzymic activity results in accumulation of delta-tocopherol and decreased gamma-tocopherol content in the seed |
728472 |
| 2.1.1.295 | physiological function |
an isoform MT-1 homozygous mutant is non-lethal and produces 24-45% alpha-tocopherol and 55-74% beta-tocopherol as compared to 96% alpha- and 4% beta-tocopherol for wild-type |
728823 |
| 2.1.1.295 | physiological function |
isoform MT-2 compensates for the loss of isoform MT-1 function, and the MT-2 mutation profoundly affects the synthesis of tocopherols without adversely affecting the synthesis of plastoquinone crucial for normal plant growth and development |

| 2.1.1.295 | evolution |
the cultivated peanut Arachis hypogaea might originate via hybridization of Arachis duranensis (A-genome) and Arachis ipaensis (B-genome), followed by a rare spontaneous duplication of chromosomes, phylogenetic analysis |

| 2.1.1.295 | metabolism |
2-methyl-6-phytyl-1,4-benzoquinol methyltransferase is one of the critical enzymes involved in vitamin E biosynthesis in plants. The enzyme can catalyze 2-methyl-6-phytyl-1,4-benzoquinol to generate 2,3-dimethyl-6-phytyl-1,4-benzoquinone. Both compounds are cyclized by tocopherol cyclase to yield delta- and gamma-tocopherol, respectively, which are subsequently further converted to beta- and alpha-tocopherol by gamma-tocopherol methyltransferase |
736187 |
| 2.1.1.295 | evolution |
the enzyme has the typical functional domains of an SAM enzyme |
756491 |
| 2.1.1.295 | metabolism |
the enzyme is involved in regulation and biosynthesis of vitamin E in safflower |
